VLSI used to have drivers like that. The SI engineers (who? me?) finally killed them because there is no way to make them stable in all applications. Now *if* this is just a nonlinear V/I curve thing, that's different. It's possible to make a driver that has a positive second derivative of current vs. voltage; those are stable and don't require anything special in IBIS. -- D. C.

Can we simply use the C_comp as input = pin capacitance or in another word, as capacitive loading at the end of = transmission line driven by drivers?

The I-V curve for input buffer seems = just describe the clamping diode behavior. Am I right? Thanks in = advance for help.

NOTE: "AR" = Action Required. -------------------------------- MINUTES ------------------------------------- INTRODUCTIONS AND MEETING QUORUM Dan Heinemeier and Cecilia Fleming of EIA called. Dan has been with EIA for 18 years and is currently a Vice President of the Government Sector and of the EIG organization under which IBIS resides. Cecilia has been with EIA for 15 years in the Engineering Department and heads several outside committees. She has been involved with several national standards efforts and is currently helping with the EIA Web page updates. Cecilia will be the primary EIA contact for the EIA IBIS Open Forum. Patti Rusher is no longer with EIA. The committee voted by acclamation to officially thank Patti for her years of service and support to the IBIS Open Forum. MEMBERSHIP UPDATE AND TREASURER'S REPORT Bob Ross reported that there are 21 Official members so far this year. He is now tracking down about 12 or so other invoices. REVIEW OF MINUTES AND AR'S No corrections were made to the minutes. The ARs will be discussed during the meeting. MISCELLANY/ANNOUNCEMENTS None PRESS AND WEB PAGE UPDATES Cecilia Fleming reported on a number of Web Page updates submitted by Syed Huq. They include updated listings for Upcoming Events through February 2000, and a link to a .pdf version of IBIS Version 3.2. Also Bob Ross noted that the roster has been updated and the recommendation note that ibischk3 be used for IBIS model checking has been added. Cecilia also noted that she is working with Syed so Syed can directly FTP documents to the EIA site. NEW MODELS AVAILABLE, LIBRARY UPDATE Kerry Nelson announced that some new Intel Version 3.1 Level IBIS models are available for the Pentium II and Pentium II/Pentium III/Xeon at: http://developer.intel.com/design/PentiumII/devtools/Index.htm http://developer.intel.com/design/PentiumII/xeon/devtools/Index.htm http://developer.intel.com/design/PentiumIII/xeon/devtools/Index.htm Bob Ross noted that AGP models are at a new location: http://www.agpforum.org/specs_specs.htm Bob reported that the Siemens models are under a new link for Infineon Technologies: http://www.infineon.com/products/ics/31/3177.htm OPENS FOR NEW ISSUES None, although some new topic discussion occurred at the end of the meeting. INTERNATIONAL/EXTERNAL PROGRESS - IEC 62014-1 (IBIS Version 2.1) - Bob Ross noted that the Committee Draft for Vote (CDV) at IEC closed on April 15, 1999. If that is successful, the next milestone for formal ratification is the draft for Draft International Standard (ADIS) phase. Cecilia Fleming will check the outcome of the CDV ballot through the appropriate EIA internal contact. - pr EIAJ ED-5302 Standard for I/O Interface Model for Integrated Circuits (IMIC) - Raj Raghuram had not further status. Bob Ross still has not heard anything regarding the planned March 22, 1999 Nikkei Electronics IBIS and IMIC article. More discussion on IBIS and IMIC occurred later in the meeting. - IEC 93/67/NP IBIS and EMC Simulation - Bob Ross talked about some preliminary documentation he received from Jean-Claude Perrin, Chair of the Working Group under IEC. The working group consists of members of the French standards organization Union Technique de L'Electricite (UTE) and also some representatives of national bodies. The documentation consists of a description, a proposed Section 10 of IBIS, an example and some results. Bob believes that the group still wants to gather internal comments and validate further the ideas before releasing them outside of the subcommittee. Bob summarized the proposal stating that Section 10, Electromagnetic Fields Computation, introduces 5 new keywords: [Core Current], [Pad Current], [Die Size], [Pad Clock] and [Clock Frequency]. The proposal shows how these keywords along with existing IBIS keywords are used for EMI field calculations. Bob is seeking permission to upload this material at an appropriate time. - JC-16.2 Subcommittee: Modeling and Test - D.C. Session noted that he is serving as a liaison with the IBIS committee and the JEDEC subcommittee. A group is working on a strawman IBIS specification for standardizing the characteristics of double data-rate SDRAMs. Cecilia Fleming was interested in the actual work item number of the activity, and she and D.C. will work off-line to get it. D.C. asked that people interested in helping to review the results contact him. Bob Ross volunteered. IBIS (EAST) USERS GROUP MEETINGS Bob Haller stated that the Scheduled April 9, 1999 meeting was not held since some participants were not available that day. The next meeting is scheduled on Friday, April 30. The delay will give more time to review the latest changes in the proposed Accuracy Specification. Bob Ross noted that the changes include adding the [Rising Waveform] and [Falling Waveform] keywords and also a revision of the defined correlation levels. Later in the meeting Arpad Muranyi stated that he is still checking on whether he can provide his set of IBIS materials for the IBIS course he is teaching on April 19-21, 1999 in Phoenix, Arizona as part of the set of tutorials of the Circuit Simulation and Signal Integrity in Microelectronic Circuits short course. Bob Ross and Kerry Nelson noted that the course was very informative. IBIS SUMMIT AT DESIGN AUTOMATION CONFERENCE Bob Ross discussed the planning for the next IBIS Summit meeting associated with the Design Automation Conference (DAC). This year the DAC is being held in New Orleans, LA at the Ernst M. Morial Convention Center. The IBIS Summit Meeting is being planned for Monday, June 21, 1999 at the adjacent Hilton - New Orleans Rivers. Normally we hold the meetings on Thursday, after the trade show, but this year because of the later dates and personal schedule conflicts, we are planning for Monday. Also Monday is a free day at DAC. Raj Raghuram added that the free show extends into the evening. While we are scheduling a full day, Bob mentioned that we typically end in the early afternoon. Bob stated that the main business is to elect EIA IBIS Open Forum officers. He expected several presentations on our current activities and plans. Arpad Muranyi stated that he might present some new ideas related to equation based modeling. Raj indicated that Dr. Norio Matsui may also present the current status on IMIC. Bob asked from the people on the conference call who might be attending, and got about a half dozen or so positive responses. Typically the meeting draws about 25 people. Bob called for a vote on holding the meeting on Monday, June 21, 1999. This was approved by unanimous vote. Cecilia Fleming has made the reservations and will now work with Bob to finalize the contract and meeting details. Bob plans for classroom seating and an overhead projector. Cecilia will handle the morning and afternoon refreshments and arrange for a lunch in the meeting room (free to participants). Bob noted that Matthew Flora will handle the sign-ups for the meeting. Some details are already on the Upcoming Events link on the EIA IBIS home page. Matthew can be contacted at mbflora@hyperlynx.com or (425) 869-2320. IBIS VERSION 3.2 EIA STANDARD PREPARATIONS Cecilia Fleming indicated that she will be initiating the official ANSI voting process. She stated that ANSI requires a 60 day voting period. As voted on the January 15, 1999 meeting, IBIS Version 3.2 will be forwarded for vote as ANSI/EIA-656A. This is an amendment to the current ANSI/EIA-656. Cecilia will work on the letter ballot form, the link to the standard, and the appropriate formal announcement for vote. Bob expected the IBIS Open Forum will provide at least one official comment related to BIRD 58 discussions later. Editorial comments and corrections will continue to be welcome. Later, Michael Cohen commented on the value of Arpad Muranyi's .pdf format of IBIS located at: http://www.eda.org/pub/ibis/ver3.2/ver3_2.pdf Michael noted that the [Voltage Range] keyword was still missing in the table of contents. [Arpad fixed this and the revised document is now uploaded.] Michael stated that this, along with the ibischk3 parser was among the most useful material on the Web site and moved that Arpad be officially thanked for his valuable contribution. This was so voted by acclamation. IBISCHK3 VERSION 3.2.2 - VERSION 3.2.5 Bob Ross announced that executables for the released version of ibischk3 Version 3.2.5 have been uploaded to http://www.eda.org/pub/ibis/ibischk3.2/ Old executables are temporarily stored at http://www.eda.org/pub/ibis/ibischk3.2_old/ This directory will be deleted in the future. Bob thanked Chris Rokusek for compiling the Unix executables, Syed Huq for the Linux executables, and Matthew Flora for the Windows executable and source code distribution. Bob called for a vote that this executable be the official release executable. Michael Cohen asked if there were any outstanding bugs, and Bob noted that BUG34 was still open. It was an enhancement which we decided to defer. It will be discussed later. The official release was approved by unanimous vote. Bob noted that more bugs may be found as we use the parser. We can do subsequent updates. Matthew Flora commented that he has been holding back on a number of minor bugs that he has encountered. Both he an Chris Rokusek know the code and can deal with many of these problems. Matthew asked if we should still be submitting bugs to the ibischk-bug reflector for Atul Agarwal to fix. After some discussion on the issue, Bob summarized the position that many of the minor bugs can be fixed by both Matthew Flora and Chris Rokusek. We should not involve Atul in these at this time. We can still involve him to help fix any problem related to the work that he did. Also, we should continue to keep Atul in the loop with any source code updates that we do. We will probably continue to use Atul for major upgrade projects, but they need to be approved by the IBIS Open Forum. COOKBOOK STATUS Stephen Peters had no status. However, a cookbook update was part of a later discussion. IBIS MODEL REVIEW COMMITTEE DISCUSSION Matthew Flora indicated no further activity. VREF, RREF, VMEAS DISCUSSION Bob Ross opened the discussion that this was a continuation from the last meeting as we ran out of time. Michael Cohen restated that he has seen, in his role as a librarian, many models where the Vref, Rref, and Vmeas were missing or unrealistic. Several people had various comments. These subparameters are different from the actual V_fixture and R_fixture values for waveform tables. Michael also stated that he has seen independent models with different Vmeas values for rising and falling responses. (This is discussed later.) Stephen Peters will supply a brief description to the IBIS reflector on this subject. Stephen will also consider expanding the Cookbook discussion. DUAL-DRIVE MODELING Bob Ross added this topic based on some reflector discussion. Both Chris Rokusek and D.C. Sessions believed that this technology could be handled by current IBIS Version 3.2 keywords. In response to a comment, Bob added that he believed that the mechanism was feedback based. The driver impedance starts low but then switches to a higher impedance such as 50 ohms to provide a good source termination. The potential benefit is a strong drive, but low noise. This could be handled using the [Bus Hold] keyword. D.C. noted that he rejected the feedback approach because it can be unstable. BUG34 - NO ERROR REPORTED FOR MISSING V/I TABLE IN OUTPUT BUFFERS As stated previously, Bob Ross noted that BUG34 is still open. Matthew Flora still needs to provide a revision per AR that states the conditions under which the warning messages will be issued. AR - Matthew Flora issue a revised BUG34 to document the conditions where Warning messages are issued. Bob again noted that this BUG34 was an enhancement that we deferred until after the ibischk3 Version 3.2.5 release because it has always existed and because it would have taken work to figure out a solution. Bob repeated from previous discussion that this fix would not capture such pathological cases such as 0 current in both tables. As part of this discussion, Milt Schwartz commented that he also uses s2iplt from North Carolina State University. He is now becoming familiar with the characteristics of various technologies. He also asked if anyone needed to do a quick scan of IBIS models. Several people including Bob, Michael Cohen and Matthew stated that this was essential. BIRD58 - DRIVER SCHEDULE KEYWORD CLARIFICATION Bob Ross stated that the planned discussion on BIRD58.1 is deferred until Arpad Muranyi has time to issue BIRD58.1 which captured the thoughts of the last meeting and of the e-mail discussion. Matthew Flora commented on the confusion and on the pathological case of having a [Driver Schedule] model with all NA delay entries. In fact only five combinations are allowed. The allowed conditions could be stated in the document. Matthew noted that if all NA's were disallowed, then a test in ibischk3 could be added. CONNECTOR PROPOSAL REVIEW Matthew Flora stated that he thought that Kellee Crisafulli and the Connector Committee were still meeting, but had no further update. Bob Ross noted that the documents have been uploaded at: http://www.eda.org/pub/ibis/connectors/ Matthew stated that he could upload some example files from the CD-ROM given out by Kellee at the January 1999 IBIS summit. ACCURACY SPECIFICATION REVIEW Bob Ross stated, as previously noted, the IBIS Users Group Accuracy Committee is reviewing an updated version of this document. IMIC AND IBIS In the remaining time the meeting was opened to some unscheduled topics. Bob introduced the IMIC and IBIS discussion that the IBIS Open Forum still needed to come up with a position statement on the relationship of the documents. The commitment was made to work together, but the nature of the relationship needed to be defined. A small committee consisting of Bob, Stephen Peters, Raj Raghuram, Norio Matsui, and Ed Sayre (plus the other officers and some other interested members) had provided input to the previously mentioned IMIC and IBIS article in Nikkei Electronics. Included were the options to consider: Merge IMIC plus IBIS (Bob thought unlikely since result would be too large) IMIC a subset of IBIS IBIS a subset of IMIC Link IBIS calls IMIC structures (and Spice structures) IMIC calls IBIS structures Independent Standards(s) IBIS translates to IBIS (already shown in the IMIC document) Only IBIS? (unlikely because of the support for IMIC) Only IMIC (unlikely since IBIS is well established) Bob also noted that a fundamental comment regarding IMIC was that while it hid the proprietary process information using the table model methodology, IMIC still appeared to require revealing the structural details for accuracy. This would be a fundamental barrier to wide-spread acceptance. IBIS perhaps could be regarded as a higher level approach that required adding some behavioral constructs for higher level detail (such as with [Driver Schedule], and Dynamic_clamps and Bus_hold). However this requires adding complexity to the IBIS standard. Michael Cohen asked how we proceed. Bob wants to continue the discussion as a scheduled agenda item in the technical section. This discussion also relates to the general Version 4.X extensions. VERSION 4.X NEW FEATURES Arpad Muranyi asked what was happening regarding the Input extensions that D.C. Sessions had been reporting. Bob Ross stated that he believes that Stephen Peters plans to work with D.C. regarding submitting a BIRD for the proposed Input detail. Bob noted that Michael Cohen may also consider some Vmeas extensions at that time regarding independent rising and falling waveform measurement points. Michael has seen this put into some models. This is not supported in IBIS Version 3.2. Arpad Muranyi elaborated on equation based modeling. Functional relationships could be added for voltage controlled and current controlled sources and scaling. Arpad thinks that this might be a solution to the current problem of requiring more syntactical extensions for more features. The Spice and IMIC approach can provide functional extensions without requiring new syntax. Raj Raghuram commented that standards such as Analog-VHDL and company proprietary equation-based syntax already exist. It is better to go with an existing standard than to invent a new one. The committee members are not too familiar with the details and status. Bob commented that the equation syntax would not only be of the IBIS model data itself, but also provide the specific algorithms to process the model. Bob stated that the EIA IBIS Open Forum is really going to be busy considering a number of new ideas. These include IMIC, the Connector Specification, EMI extensions, the Accuracy Specification and the specific Version 4.X features that will be proposed.

Here it is. This text will also appear in the next edition of the cookbook. Regards, Stephen Peters Intel Corp. -------- 1. What are Vmeas, Rref, Cref and Vref? Vmeas, Rref, Cref and Vref represent the output loading conditions under which a devices Tco (propagation delay or clock-to-output timing) is specified. These parameters are sometimes referred to as the 'timing test load', and are documented in a devices data sheet. Please note that the timing test load does not necessarily represent the load the device sees in a real application. It is simply the output load the manufacture uses when characterizing a devices performance. Vref ------ | \ / Rref +-------+ \ | | | -----| DUT |------------+ | | | +-------+ ---- ---- Cref | gnd As shown above, Vref represents a pullup voltage, Rref represents a load resistance connected to Vref, and Cref is a load capacitance to ground. Vmeas is the point on the output waveform at which a Tco measurement is referenced to. As an example, if Tco (clock to output) for a particular device is 5ns, this means there is a 5ns delay from when input clock waveform crosses a specific voltage level to when the output responds by crossing 'Vmeas' volts. See the diagram below. +--- Tco ----+ | | | ___________|_____________ |/ | Input + | ________/ | | | ______________________ |/ Output ---+------- Vmeas _____________________/ 2. So why are these parameters included in an IBIS file? The timing test load parameters are included in an IBIS file to aid the user (or simulator) in doing system level timing analysis. Given that a device has a specified propagation delay into the timing test load, the user can simulate the device as it drives this load and determine how long it takes the output to switch from quiescence to crossing 'Vmeas' volts. The user can then do a second simulation with the device driving the actual load, and by noting the difference in time it takes to cross 'Vmeas' the user can determine the difference in device propagation delay due to output loading. This is a major factor when doing system level timing analysis.

References: <199904260235.TAA24985@smtp.nwlink.com> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Following on from Kellee's message, I can confirm that the Happy99.exe is infected with the W32/SKANEW virus. This is a new virus (so update your virus scanning software). Here is the Data from the Virus Alert Labs http://www.avertlabs.com/public/datafiles/valerts/vinfo/w32ska.asp W32/Ska (A.K.A. Happy99.exe) W32/Ska is a worm that was first posted to several newsgroups and has been reported to several of the AVERT Labs locations worldwide. When this worm is run it displays a message "Happy New Year 1999!!" and displays "fireworks" graphics. The posting on the newsgroups has lead to its propagation. It can also spread on its own, as it can attached itself to a mail message and be sent unknowingly by a user. Because of this attribute it is also considered to be a worm. AVERT cautions all users who may receive the attachment via email to simply delete the mail and the attachment. The worm infects a system via email delivery and arrives as an attachment called Happy99.EXE. It is sent unknowingly by a user. When the program is run it deploys its payload displaying fireworks on the users monitor. Note: At this time no destructive payload has been discovered. When the Happy.EXE is run it copies itself to Windows\System folder under the name SKA.EXE. It then extracts, from within itself, a DLL called SKA.DLL into the Windows\System folder if one does not already exist. Note: Though the SKA.EXE file file is a copy of the original it does not run as the Happy.EXE files does, so it does not copy itself again, nor does it display the fireworks on the users monitor. The worm then checks for the existence of WSOCK32.SKA in the Windows\System folder, if it does not exist and a the file WSOCK32.DLL does exist, it copies the WSOCK32.DLL to WSOCK32.SKA. The worm then creates the registry entry - HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce\Ska.exe="Ska.exe" - which will execute SKA.EXE the next time the system is restarted. When this happens the worm patches WSOCK32.DLL and adds hooks to the exported functions EnumProtocolsW and WSAAsyncGetProtocolByName. The patched code calls two exported functions in SKA.DLL called mail and news, these functions allow the worm to attach itself to SMTP e-mail and also to any postings to newsgroups the user makes.
