For > parsing purposes should this be an error or a warning ? I vote for Warning, since the simulator should ignore them anyway. > Similarly, is it OK for the user to specify only Vinl and not > Vinh and vice versa ? Yes. The reason that this is OK is that the original "Vinh =" and "Vinl =" subparameters are still required for Input and I/O model types. These can serve as a default for values that are not specified. However, this would not be a recommended practice. > 2) I am assuming that the Pulse_low and Pulse_high expect at least > the thresholds or the hysteresis thresholds to be specified, else > it will be flagged as an error. Is this correct ? That is correct. However, as noted above, all Input and I/O models will have a Vinh and Vinl subparameters, even if they are the default. If Pulse_high and Pulse_low are included in one of the Output model types which does not have a Vinh or Vinl subparameter, then it is good to flag this as an error. Either the Model_type was incorrect, or the Pulse_high and Pulse_low subparameters were incorrectly entered. > 3) The spec refers to [End Electrical Description] to terminate > the EBD model in some places while in other places it refers to > [End Board Description].

Perhaps this should also > be highlighted in the document. Correct, the [Model Selector] name shall not be [Model] name nor shall it be any reserved word. This would be an Error. We have had a discussion in the past whether any of the models listed in the first column of [Model Selector] could be any of the reserved words - such as NC or GND or POWER. This should probably be allowed since these are allowable models. It is conceivable for buffers to be switched in a disconnected mode or connected to a fixed voltage for some configurations. Simulators may have difficulty in dealing with this type of flexability since power/ground nets can operate under different rules than signal nets, and having switchable topology can introduce major complications for this additional feature. One real functional extension beyond this which is not supported by IBIS Version 3.0/3.1 is using such a feature to convert differential pins into a single-ended configuration. However the [Diff Pin] keyword itself was never intended to create a diffential model using one side a reserved word model (GND or POWER). > 7) Are there any special semantic checks for the models/information > specified under the [Driver Schedule] keyword besides those specified > in the document ? For example, the spec states that the models > under the Driver Schedule are typically Open Sink (Open Drain) or > Open Source. Should there be any such checks ? Not at this time. I do not think we need to add such restrictions since the "next generation" ideas could invalidate them. Also totem devices with one side very weak would be a practical possibility. > Thanks > atul From owner-ibis Fri Jan 9 10:19:13 1998 Received: from hyperwall.hyperlynx.com (root@mail.hyperlynx.com [209.20.148.70]) by server.vhdl.org (8.8.5/8.8.3) with ESMTP id KAA00697 for ; Fri, 9 Jan 1998 10:19:12 -0800 (PST) Received: from tensor (tensor [209.20.148.75]) by hyperwall.hyperlynx.com (8.8.5/8.8.5) with SMTP id DAA11582 for ; Fri, 9 Jan 1998 03:18:08 -0800 Message-Id: <3.0.5.32.19980109101645.0098ccc0@mail.nwlink.com> X-Sender: mbflora@mail.nwlink.com X-Mailer: QUALCOMM Windows Eudora Pro Version 3.0.5 (32) Date: Fri, 09 Jan 1998 10:16:45 -0100 To: ibis@eda.org From: Matthew Flora Subject: Interrupted discussion of BIRD 46 Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" All, This morning's IBIS Open Forum meeting was cut off in mid-discussion of BIRD 46.

Of course, if the system is sharing a FAT volume it'll be limited to 8.3, but what most NT users see is strictly a shell effect in directory listings; programs have full access to the long filenames. Note that the 8.3 limitation when accessing FAT volumes applies to 4.x as well, since NT doesn't use the Win95 hidden filename extensions. Bottom line: NT3.5 doesn't need special consideration here; it handles long names quite nicely. (Says, DCS, who used to administer NT3.5 systems.) -- D. C.

Is there still a problem with files with capitol letters in the file name? I know that there is a problem for WIN95 file systems. I think there is still a inherent inconsistency between how NTFS and Unix files systems view file names that have "white space" or capital letters or perhaps even other special characters (like "*" or "\"). jon From owner-ibis Tue Jan 13 01:29:21 1998 Received: from jester.ti.com (jester.ti.com [192.94.94.1]) by server.vhdl.org (8.8.5/8.8.3) with ESMTP id BAA29939 for ; Tue, 13 Jan 1998 01:29:20 -0800 (PST) Received: from dfrp01.itg.ti.com ([137.167.210.12]) by jester.ti.com (8.8.8) with ESMTP id DAA27688 for ; Tue, 13 Jan 1998 03:26:27 -0600 (CST) Received: from ti (CNA0819696.business.tide.ti.com [137.167.202.100]) by dfrp01.itg.ti.com (8.8.7/8.8.7) with SMTP id RAA13238; Tue, 13 Jan 1998 17:08:14 +0100 (MET) X-Mailer: BeyondMail for Windows/Professional 2.3 MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7Bit To: ibis@vhdl.org From: Hans M Hilbig Subject: unsubscribe Date: Tue, 13 Jan 1998 10:29:37 -0800 X-BeyondMail-Priority: 1 Message-Id: Conversation-Id: <3.0.32.19971223095232.00dd6848@loki.wcdf.viewlogic.com> In-Reply-To: <3.0.32.19971223095232.00dd6848@loki.wcdf.viewlogic.com> Reply-To: Hans M Hilbig Cc: Heribert Erhart , Hans-Gerhard Baumann , Peter Weber X-MISTI-OPTIONS: EgnuMA2R+~*fBABHBxAbcSHtAB|B)R!A,BD|fABACsGbA X-Receipt-From-Agent: true unsubscribe ************************************************* MSP430 Engineering, 1394/CDC/AAP Lab Texas Instruments Freising Phone: +49-8161-804126 FAX:+49-8161-804909 e-mail: h-hilbig@ti.com From owner-ibis Tue Jan 13 09:56:45 1998 Received: from mailgate.cadence.com (mailgate.Cadence.COM [158.140.2.1]) by server.vhdl.org (8.8.5/8.8.3) with ESMTP id JAA09109 for ; Tue, 13 Jan 1998 09:56:45 -0800 (PST) Received: (from smap@localhost) by mailgate.cadence.com (8.8.5/8.6.8) id JAA08483; Tue, 13 Jan 1998 09:54:24 -0800 (PST) Received: from golf.cadence.com(158.140.103.42) by mailgate.cadence.com via smap (mjr-v1.2) id xma884714062.008473; Tue, 13 Jan 98 09:54:22 -0800 Received: from pc-gpf (d158140105143 [158.140.105.143]) by golf.Cadence.COM (8.7.3/8.7.3) with SMTP id MAA01123; Tue, 13 Jan 1998 12:54:19 -0500 (EST) Message-Id: <3.0.1.32.19980113125128.00951a60@golf.cadence.com> X-Sender: gpf@golf.cadence.com X-Mailer: Windows Eudora Pro Version 3.0.1 (32) Date: Tue, 13 Jan 1998 12:51:28 -0500 To: ibis@vhdl.org, ibis-user@eda.org From: "Gregory P.

MEMBERSHIP UPDATE AND TREASURER'S REPORT Patti Rusher reported that she will prepare invoices for the 1998 membership and bring them to the IBIS Summit meeting for distribution. Then she will mail out the rest. Bob Ross indicated that there were two new potential members to be invoiced. Patti will give copies of the invoices to Bob for tracking and address validation. Bob reported no change in the $6008 in the account. However, the next year Design Automation Conference EIA participation will be deducted from this figure plus other administrative expenses - effectively zeroing out the account. REVIEW OF MINUTES AND AR'S No corrections were made. Bob Ross indicated that the AR's will be discussed during the meeting. MISCELLANY/ANNOUNCEMENTS Note: Effective Monday, January 12, 1998 as a result of the relocation of Interconnectix to the Mentor Graphics site, Bob Ross will have a new e-mail, telephone, and mailing address. They are noted at the end. The old e-mail bob@icx.com should still work for many months. Bob reported that the Majordomo conversion has been delayed until after the relocation, but it is still planned. The Signal Integrity reflector list uses Majordomo. PRESS AND WEB PAGE UPDATES Syed Huq reported that Cadence Logo has been updated on the EIA IBIS home page in the Poster section. Syed also reported that Mitsubishi has submitted its logo and has provided an IBIS Model link. This will be updated in the pending a written permission on a company letterhead. Mitsubishi's roster and contacts.txt entries have been updated. Matthew Flora asked what is needed to change logos since the HyperLynx logo may be updated. Bob and Syed responded that a written permission letter on a company letterhead is required to be sent to Jon Powell with a copy to Syed (addresses are at the end) so that there is a hard copy record that the usage of the company logo was properly authorized. Bob mentioned that the Interconnectix logo will probably remain, even though Interconnectix is a business unit of Mentor Graphics (and the Interconnectix EIA IBIS Open Forum membership applies to Mentor Graphics by EIA rules). Zeelan Technology, also a unit of Mentor Graphics, may also have a separate logo based on its Mentor Graphics relationship. C. Kumar will check whether Cadence wants to retain the Unicad logo. Bob is in favor of allowing all of the relevant company logos associated with the same EIA IBIS Member company. Bob also reported that Altera has updated its contacts.txt entry indicating IBIS models are under development. NEW MODELS AVAILABLE, LIBRARY UPDATE Bob Ross reported that the Mitsubishi IBIS Model Memory Library with about 80 files is now available at: http://www.mitsubishichips.com and click "Technical Info" to go to http://www.mitsubishichips.com/data/files/download.cgi?ibis.htm http://www.mitsubishichips.com/data/ibis.html Bob reported that the Samsung link for SRAMs has been changed from a request form to an actual model site at along with a revised request form: http://www.sec.samsung.com/Products/sram/sram_model.html http://www.sec.samsung.com/Products/sram/req_model.html Bob also reported that the Texas Instruments Logic Library IBIS model site has been updated. OPENS FOR NEW ISSUES Bob Ross on BUG20 - Crash with Windows95 multiple filename extensions Bob Ross on BUG21 - Drive Warning with NA Data in Min and Max Columns Bob Ross on IBIS Model Review Committee Discussion ADMINISTRATIVE DETAILS Bob Ross discussed some beginning of the year archive and cleanup details. The last set of minutes that are archived for 1997 contain the participation list and IBIS Membership List for 1997. A new list for 1998 will begin with the IBIS Summit attendees. All current members on the Voting Members list will be retained until we go through the membership renewal cycle, but those on the Others Participants will be dropped to eliminate changed entries and keep track of 1998 participation. The 1997 Roster and Contact lists have been archived for 1997. INTERNATIONAL PROGRESS - IEC 62014-1 (IBIS Version 2.1) - Bob Ross reported that Patti Rusher states that the document is being circulated, so the official acceptance may take months. However, since there are no issues, its approval is expected to be automatic. When approval is reached, the IEC nomenclature will be added to the ANSI/EIA-656 document. Patti will then issue a press release. - EIAJ III (I/O Interface Model for ICs) - Bob reported that he got an update from Dr. Hideki Fukuda (now a Director at Hitachi), Chair. of the subgroup, that Draft 1.0 is scheduled for a January or February, 1998 release. The project was presented at an IEC TC93 meeting in September, 1997 in Tokyo, but he did not request for nor is aware of any formal IEC TC93 project number. - IBIS and EMC Simulation - Bob reported that this activity is being resurrected under Jean-Claude Perrin of Texas Instruments in France. He has called for national representatives to meet in Paris on March 3-4, 1998. Bob is the designated US representative. Bob has requested more details. He invited Jean-Claude to the European IBIS Summit. He also suggested privately holding a meeting on Friday, February 27, 1998 after the IBIS Summit meeting to align better with travel schedules. Bob could serve as an information liaison to monitor the activity, but would want assistance for technical contributions. Everyone supported this position since there were no volunteers for being the actual representative. IBIS EAST MEETING Bob Ross reported that the next meeting is scheduled on Thursday, January 15, 1998 at 3:00 PM at Stratus Computer. A notice has been sent out to the ibis-users reflector. The agenda includes reports on sub-group activities and Summit participation topics: Greg Edlund (Digital Equipment) on IBIS Model Validation/Accuracy Paul Galloway (Cadence) on Software Aspects of IBIS as it Effects the User Community IBIS Summit Discussion DESIGNCON98 IBIS SUMMIT Syed Huq provided an update on the IBIS Summit meeting planned on Monday, January 26, 1998 and hosted by National Semiconductor at the same location as DesignCon98. The meeting will be at a room in the Westin Hotel adjacent to the Santa Clara Convention Center. Syed reported that he sent out a final call for attendance confirmation for luncheon budgeting and would like an RSVP by January 12, 1998. So far 29 people are signed up and Syed noted the companies represented. The meetings typically attract 35-45 people. Syed requests the presenters to provide soft copies of their presentations to him by January 19, 1998 so he can make copies available. Otherwise the presenters are expected to bring 40 copies for distribution at the meeting. Syed expects to finalize the agenda January 13 or 14, 1998. Currently he and Bob Ross reported on eight planned presentations. Kellee Crisafulli (HyperLynx): A New IBIS development Tool Kit Greg Edlund (Digital Equipment): Developing an IBIS Model Quality Specification. Paul Galloway (Cadence): Data Requirements to Build a Complete IBIS Model - Experience from Cadence's Model Development Process C. Kumar (Cadence): Problems Using VT Curve Models in Simulation Arpad Muranyi (Intel): Comparing the Performance and Accuracy of SI and IBIS models in High Frequency Simulation Patrick Riffault (Cadence): Correlating a Simulated model (Spice2IBIS) to Lab Measurements Bob Ross (Interconnectix): Inspecting IBIS models Ed Sayre (North East Systems Associates): East Coast IBIS Activity Updates Bob Ross reported that some current activities will also be discussed at the Summit meeting. DESIGNCON98 DesignCon98 (formerly Design SuperCon) is scheduled Tuesday-Thursday, January 27-29, 1998 at the Santa Clara Convention Center. DesignCon98 information is available at: http://www.designcon.com Syed Huq reported a 20% IBIS Member discount for employees of OFFICIAL EIA IBIS Open Forum Member companies. Details were sent out. The official member companies are the first 22 Voting Member companies (including all divisions) at the top of these minutes. Bob Ross reported that there are three presentations in the Signal Integrity track that relate to IBIS Models on Tuesday, January 27. Also on Tuesday at 4:30 PM, there will be one hour panel session discussion: IBIS Panel - How Good are the Currently Available IBIS Models? Moderator: Jim Lipman, EDN Magazine Participants: Kellee Crisafulli, HyperLynx Paul Galloway, Cadence Bob Haller, Digital Equipment Syed Huq, National Semiconductor Jon Powell, View-logic Bob Ross, Interconnectix Ed Sayre, NESA DATE98 (DESIGN AUTOMATION AND TEST IN EUROPE) IBIS SUMMIT The DATE98 Conference will be held Monday thru Thursday, February 23-26, 1998 in Paris France. Several IBIS and PCB Design related activities are being planned. The DATE Conference itself is the continuation of EuroDAC (with EuroVHDL) and ED&TC (EDAC, ETC, and EuroASIC). More information is available at: http://www.date-conference.com - IBIS Fringe Meeting - Tuesday, February 24, 1998 Bob Ross mentioned that because of other activities, such a general interest meeting similar to the Design Automation Conference "Birds of the Feather" meetings is very unlikely. IBIS is already widely known. If one is held, it will be called at the last minute. - PCB Symposium - Wednesday, February 25, 1998 Bob reported that the DATE committee and Fachverband Elektronik-Design e.V. (FED) joined the seven companies (Cadence, Incases, Mentor Graphics, VeriBest, Viewlogic, Xynetix, and Zuken-Redac) as co-sponsors of this vender-neutral (i.e., no product promotion), informative, all-day event. Bob outlined the currently planned program which is scheduled from 10:00 AM to 4:00 PM: 10:00: Opening Address, Lutz Treutler of the FED 10:15: Viewlogic, (not determined yet) 10:45: Mentor Graphics, Bob Ross 11:15: Xynetix, Andrew Jones 11:45: Incases, Torsten Maeser and Werner Rissiek 12:15: Buffet Luncheon 1:30: VeriBest, David Weins 2:00: Cadence, Paul Galloway 2:30: Zuken-Redac, Anthony Cutler 3:00: Round Table Discussion Bob indicated that all of the presentations cover some aspect related to PCB design. He mentioned the contents of each. Bob's presentation will be "Getting IBIS Models". The Round Table Discussion will have representatives from several simulator companies and also former EIA IBIS Open Forum Chair. Will Hobbs. - European IBIS Summit - Thursday, February 26, 1998 Bob reported that Cadence. High Design Technology (HDT) and Mentor Graphics are co-sponsoring the IBIS Summit meeting scheduled on Thursday, February 26, 1998. A buffet lunch will be provided for attendees. Bob will be sending out another notice and requests RSVP for attendees. So far the program includes five presentations: John Fitzpatrick (Alcatel): Use of IBIS in Alcatel Werner Rissiek (Incases): IBIS and Radiation Analysis Syed Huq (National Semiconductor): IBIS Model Development at National Bernhard Unger (Siemens): SI-Analysis with HSPICE Based on IBIS Behavioral Models Razvan Ene (HDT): IBIS Models for EMC and High-Frequency Devices Other presentations are still being solicited or are pending travel approval. C. Kumar indicated that he would do his presentation: C. Kumar (Cadence): Problems Using VT Curve Models in Simulation Bob indicated that he may also do a presentation and continue to solicit some other presentations and set up some discussion topics. Bob looks forward to an interesting and productive technical exchange between U.S. and European technical experts since several US IBIS participants will be attending. S2IBIS2 Bob Ross reported that he has no further information on s2ibis2 activities from R. Sanjeev (Presi) since last meeting when Presi requested test cases for ECL devices. The Veribest AR regarding s2ibis2 for NT remains. AR - Ian Dodd put s2ibis_ver2.1 for Windows on the VeriBest Web site. EDITING COMMITTEE Bob Ross plans to put an unofficial IBIS ver3_1b.ibs update in the /pub/ibis/wip directory of eda.org to correct some editorial errors and also to deal with the [End Electrical Description] and [End Board Description] nomenclature inconsistency reported later by Atul Agarwal. The BNF AR remains. AR - Bob Ross generate and post a BNF for IBIS Version 3.0 (and IBIS Version 3.0 ratification AR). BIRD44 - INTERPRETATION OF MIN/MAX/WEAK/STRONG DATA Bob Ross opened the discussion on BIRD44 which was submitted just prior to the June 1997 IBIS Summit meeting by Andy Ingraham. BIRD44 proposes changing the min and max column headings for certain keywords to slow/weak and fast/strong for IV tables and [Temperature Range), and also to slow and fast for [Ramp] and Waveform tables. This would apply only to the comment lines that are used for column headings and to any related discussion in the Specification. A general discussion followed. Most people favored this change since it would add to the clarity of the document. The min and max headings would would be retained for column headings which have columns whose entries are sorted by magnitude. Bob presented a possible alternative of putting a note in the initial syntax rules and guidelines section. Arpad Muranyi felt that such information would be missed. Arpad questioned whether this would effect how simulators would process the data. Bob and others indicated that this was just an editorial change. The simulators do not process the comment lines and already deal with the min and max column interpretations for specific keywords. C. Kumar questioned whether this applied to C_comp could be related to models. Stephen Peters indicated that there is lose or no correlation, and the C_comp subparameters entries are by magnitude. Bob indicated that simulators would be expected to use the C_comp max entry with the slow/weak corner, and the min entry for the fast/strong corner. The other columns under the [Model] keyword tend to be correlated. In particular, the [Ramp] and Waveform columns are expected to be correlated directly with the IV table columns. The max waveform table would not be used with the min IV column. The original private and public model generation and processing tools (s2ibis, ibischk, etc.) would still be generate and report on models using the original min and max column heading notation. Bob indicated that BIRD44 was proposed in terms of the IBIS Version 2.1, but that other keywords in IBIS Version 3.0 may need to be considered. Bob also gave some options and alternatives to BIRD44 including (1) reject (do nothing) (2) add a note (which most did not favor), (3) adopt, and (4) adopt with revision such as standardizing on just slow/weak and strong/fast for all of the revised headings to show correlation, and (5) adopt with a combined syntax such as min-slow/weak, max-fast/strong for maximum consistency. Bob plans to put BIRD44 for resolution and vote at the February 13, 1998 teleconference meeting. Matthew Flora stated that he would help revise the Version 3.1 drafts to include the BIRD44 clarifications. Bob will plan this as an unofficial ver3_1c.ibs release to keep this change isolated from the vers3_1b.ibs corrections. The general consensus is to make BIRD44 type clarifications. IBISCHK2+ (VER 2.115) PROGRESS Matthew Flora fixed BUGs 9-18 per the AR of the last meeting for a Version 2.1.15 ibischk2+ release. Chris Rokusek received a version of the source code, but was not sure it was the latest version. Chris will create a set of executables for different operating systems for Bob Ross to post on eda.org. Matthew will work with Chris to get the latest version (after BUG20 and BUG21 are fixed - discussed next). Bob verified with Matthew that BUG8 was not included in the set of fixes. BUG20 - Crash with Windows95 Multiple Filename Extensions Matthew Flora indicated that a crash in ibischk2+ occurred when the file was stored in a text1.text2.ibs file on Windows NT. Bob Ross asked whether this crash also occurs on a Unix system, and Matthew did not know. Matthew identified the source of the problem. Bob classified the bug as Severe, Medium, Open because it caused ibischk2+ to crash. Matthew said he plans to fix it before sending Chris Rokusek the source code. BUG21 - Drive Warning with NA Data in Min and Max Columns Matthew Flora and Bob Ross found that ibischk2+ issues a voltage drive warning message for min and max columns even when the min and max IV tables and VT tables contain all NA entries. Chris Rokusek stated that it would be easy fix since the parser can test for this situation. the parser would issue a warning message only if any of the columns contained data. Bob classified this as ANNOYING, LOW, OPEN. Chris plans to fix this bug prior to releasing the ibischk2+ executables (designated Version 2.1.15). AR - Matthew Flora fix BUG20 and send the revised source code to Chris Rokusek. Chris fix BUG21 and generate ibischk2.1.15 executables for various operating systems. Chris sent the executable file to Bob Ross. Bob put these new executables in the /pub/ibis/ibschk2+ directory under eda.org. VERSION 3.1 PARSER DEVELOPMENT Bob Ross reported that he responded to some questions sent by Atul Agarwal of APT Software Avenues Pvt Ltd. on the ibischk-bug@eda.org reflector for the review committee and copied the response to the ibis@eda.org reflector. Atul discovered the [End Board Description] and [End Electrical Description] nomenclature inconsistency. Bob favored the first choice. Stephen Peters concurred since it was parallel to the [Begin Board Description] syntax. Bob will make this correction in the unofficial ver3_1b.ibs document. Bob and Stephen will need to work on the test matrix and also will need some test examples. COOKBOOK No report, all the ARs are carried forward. AR - The following people have volunteered to supply examples Steve Kaufer/Hyperlynx -- Example 1 (Version 1.1 basic model) Arpad Muranyi - Example 2 Stephen Peters - Example 3 AR - Syed Huq. Review and expand (if necessary) Section 3.3. on "Obtaining I/V and Switching Information via Lab Measurement". IBIS MODEL REVIEW COMMITTEE DISCUSSION Bob Ross indicated that the CAE Vendor IBIS Model review sub-group needs additional members from other vendors. So far Bob and Matthew Flora have joined. Olaf Rethmeier and Chris Rokusek stated that they would join. Bob expects a representative from Cadence and VeriBest. Matthew Flora remains as the contact person regarding this sub-group at mbflora@hyperlynx.com. D.C. Sessions stated that VLSI will provide IBIS models to CAE vendors for for the purpose of review and feedback directly to VLSI. The models are not to be distributed. D.C. would require a written request to him at the address on the Roster. Bob will continue the discussion of the review activity as an agenda topic at the IBIS Summit meeting since it is related to the general set of topics at the meeting. BIRD42.3 - MODELING CURRENT WAVEFORMS C. Kumar indicated that his presentation at the IBIS Summit Meeting on January 26, 1998 will provide additional discussion related to BIRD42.3. BIRD45 - DYNAMIC CLAMPS Bob Ross mentioned briefly that we still need to follow up on the previous suggestion by Dave Moxley to investigate using [Driver Selection] as part the description. Arpad Muranyi needs to work with Neven Orhanovic on this subject. BIRD46 - RELAXATION OF SOME IBIS FILE NAME RESTRICTIONS In the time remaining Matthew Flora introduced BIRD46. He noted that the original "8.3" filename.ibs limitation based on the original DOS naming restriction was becoming obsolete in practice. Users have migrated to Windows 95/NT which does not impose such a limitation. Also, longer file names which include periods would be clearer. The final .ibs extension would still be required. Matthew noted that there exist 64 total character limit in the Windows NT Windows NT documentation that is included in BIRD46. George Opsahl cautioned that the DOS limitation might still exist in Windows NT 3.5. Matthew stated that he did not see the problem since longer named files were shown along with the truncated form. The longer named files were accessible. Bob Ross noted that this change should also need to be considered for .pkg and .ebd files for consistency. This discussion will continue at a later meeting. NEXT MEETING: The next meeting is the EIA IBIS Summit in Santa Clara, CA on Monday, January 26, 1997. No teleconference connection is planned. The next teleconference meeting is on Friday, February 13, 1998, 8:00 A.M. to 9:55 A.M. ============================================================================== NOTES IBIS CHAIR: Bob Ross (503) 685-0732, Fax (503) 685-4897 bob_ross@mentorg.com Modeling Engineer, Interconnectix BU of Mentor Graphics 8005 S.W.

I have been working on the circuit simulation and modeling area and right now in charge of setting up IBIS model in our company. We have two questions for generation method of IBIS modeling. Please let me know any comments or recommendations for following: 1. Pullup/Pulldown I/V characteristics Which method is more reasonable between A and B method? A approach: S2ibis2 from NCSU uses only one netlist file for simulation. For example, there are four elements, pullup and pulldown tr., power and ground clamp, in ouput type buffer. When S2ibis2 simulates a defined buffer netlist for pulldown I/V characteristics, it controls only gate bias of pullup tr. and pulldown tr.. So, it is consist of pullup I/V characteristics and pulldown tr. characteristics as ground clamp, and vice versa. B approach: We can get the pullup characteristics without pulldown tr. and ground clamp. Also we can get the pulldown characteristics vice versa. In result, there is only pullup I/V characteristics consisted of pullup tr. and power clamp. 2. Is there a convert program(commercial and public domain) from IBIS model to HSPICE(or spice) format. If you know the program, please let me know it. Sincerely.

Sponsors: Mentor Graphics, Cadence, High Design Technology DATE98 Show: DATE98 - February 23-26, 1998. The IBIS meeting is scheduled the day following the last day of the trade show portion of the Conference. See www.date-conference.com for more information. PCB Symposium: An all day symposium is scheduled Wednesday, February 25, 1998, 10 AM - 4 PM on PCB design issues. This is being co-organized by seven EDA vendors: Cadence, Incases, Mentor Graphics, VeriBest, Viewlogic, Xynetix, and Zuken-Redac. An informative, vendor-neutral program and panel sesson is scheduled. Plan to include DATE98, the PCB Symposium, and the IBIS Summit Meeting in your visit. Registration is required. You can register through several EDA vendors in Europe, through the DATE98 web site or else by e-mail to cweiss@cadence.com BACKGROUND As a result of regular EIA IBIS Open Forum meetings since 1993, IBIS Version 2.1 has been ratified both nationaly (in the United States of America) as ANSI/EIA-656 and internationally as IEC 62014-1. Most of the IBIS are conducted on a regular basis via teleconferencing, but the EIA IBIS Open Forum also conducts two face-to-face meetings every year at the Design Automation Conference (DAC) and DesignCon locations. While some of the IBIS Summits focused on resolving standards issues, others have been used for general IBIS information exchange. Historically, some of the IBIS advances have come from such exchanges. Because of wide-spread international usage and acceptance of IBIS, the EIA IBIS Open Forum will hold a European IBIS Summit at the same time as the DATE98 Conference and PCB Symposium in Paris, France. We are particularly interested the international experiences and ideas at this IBIS Summit. CALL FOR PARTICIPANTS People involved in IBIS Model development, EDA tool development, and digital circuit design are invited to participate in the European IBIS Summit meeting.
