Directions to NESA at end of this message Agenda: * IBIS Accuracy Specification Status * IBIS Connector Model Status Preparation for upcoming IBIS Summit (at DesignCon99, Santa Clara, CA, February 1, 1999) * IBIS WEB page * Any other business What is IBIS**IBIS WEB Page**IBIS User Group Activities IBIS = I/O Buffer Information Specification The design community primarily uses electronic design tools and SPICE (Simulation Program with Integrated Circuit Emphasis) to develop and test the viability and performance characteristics of their designs. The IBIS standard is an alternative method of simulation for high speed designs that uses behavioral models verses transistor level models. IBIS Web page located at : http://www.eigroup.org/ibis/ibis.htm We had a well attended and informative IBIS Summit in October and now it is time to get going with the IBIS user meetings again. The IBIS Users group continues to move forward with the IBIS Accuracy Specification and test board,IBIS Connector modeling and training initiatives. We are hoping for additional involvement from the engineering community in 1999 and are looking for input, involvement and ideas. Do you want to come up to speed and learn about IBIS...? Do you want to develop/investigate a particular IBIS related idea that would assist with your system designs...? Do you want to share your experiences using IBIS models and get feedback...? Do you want to get generally involved in the current IBIS User group discussions...? Please feel free to join the IBIS User group meetings - all are welcome, in person or by conference link! Let Kathy Breda (breda@nesa.com) know if you would like to attend so we have enough chairs and brownies! Also, if you would like to connect via conference phone, please let Kathy know and she will arrange the details. Additional names have been added to the IBIS distribution list, so if you did not attend the Summit and need copies of the presentations, you can get them off the IBIS web page (URL listed above) or contact Kathy.

It has been discussed at meetings and briefly on the IBIS reflectors. Also, several comparison studies with Spice simulations have been discussed at meetings. Vendor specific issues such as HSPICE offerings should be discussed on the Signal Integrity reflector (where the message was also sent) or with the vendor directly. The question related directly to HSPICE, which is one vendor's commercial implementation of Spice. As a general policy, the IBIS reflectors avoid vendor-specific discussions because of EIA guidelines. However, I believe that implementations of IBIS in Spice using behavioral constructs that are commonly available in several Spices is an appropriate topic for ibis-users@eda.org reflector. The formats for tables seem to be unique for different commercial versions of Spice, so the discussion may have to use one vendor's Spice for illustration. However, since the tables can be translated or made equivalent in other versions of Spice, I feel the substance of the discussion is sufficiently generic. I refer to the following documents which are archived for further reference on this issue of behavioral implementation of IBIS in Spice. http://www.eda.org/pub/ibis/summits/feb98/unger.zip and the IBIS email reflector archives of October 1997 which shows a prototype implementation. http://www.eda.org/pub/ibis/email/email97/email.oct97 Best Regards, Bob Ross Mentor Graphics Chair., EIA IBIS Open Forum > Date: Tue, 19 Jan 1999 17:26:11 -0700 > From: "steve_monroe@stortek.COM" > To: ibis@eda.org > Subject: Re: Using Ibis models in hspice > Kellee Crisafulli wrote: > >Hi Steve, > > > > This is a question for the simulator company you > >are using and should not appear on this IBIS reflector. > >Please redirect you question directly to your simulator > >company. > > > I disagree completely.

R_ref is for board level timing adjustment while R_fixture partially defines the environment in which the rising and falling waveforms were measured. I good simulator could scale the time waveforms if the resistance of the simulation environment is different than the measurement environment.

Does the C_comp include Pad Capacitance or is it just the capacitance of the buffer on the silicon after the pad? It should include everything that you would see if you looked into the die at the pad. That is C_pad, C_metal, C_tranistor, etc. ii) How can I generate for a buffer different IBIS Models if the buffer has different modes like; Power Down, Normal Operation or Clock Stop? Use the [Model Selector] keyword and list all models that can be used on a pin in it. iii) How can I generate for a buffer which has a differential input and differential output? Use the [Diff Pin] keyword to associate two otherwise independent models as differential.

When I add the keyword [Voltage range] and > set it to 5v , the sweep goes from -5v to 10v but also re-defines my core > supply to 5v when it should stay at 3.3v. Any ideas on how to get s2ibis2 to do the -5v to 10v sweep while maintaining the core power supply at 3.3v ? Thanks!
