This is for discussion at the IBIS User Group meeting being held this coming Thursday, December 4, 1997 at 3:00. The meeting is being held at Cadence in Chelmsford, MA. If you haven't already done so and are interested in attending, let me know ASAP. Thanks, Kathy Breda ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ As a fallout of the IBIS Users' group meeting in September, the following three major topics are suggested to be addressed by sub-committees to be proposed at the December 4th meeting: 1) IBIS user documentation, IBIS Syntax, File Formats and Converters SPICE to IBIS and IBIS to SPICE - Who's doing what to whom, where and when. 2) Validity of IBIS based results and the context where they are computed: a) Engineering oriented simulations, trade studies, technology selection b) Post layout board validation for proper device operation, PWB design rules, crosstalk, clock and bus performance estimations and validations, etc. 3) Tools Validation. Which tools do what better than others? Does one size fit all? Is there an inexpensive way to find out? The latter topic is somehwat touchy since it involves the tools vendors and requires that objectivity be maintained in strictest confidence. The other topics are all close to what we discussed before and can proceed in the usual and customary committee settings. Don Tellian suggested that we not regionalize the Users' group and I am in concurrance. However, in order to get it off the ground, a little NE concentration will help get things going and then we can generalize membership.

Discussion Topic 1: ------------------ The meeting began with Greg Edlund and Bob Haller, both of Digital, presenting their thoughts on IBIS model Accuracy. They discussed the need for the market to really drive the requirement for model accuracy and that users need to consider making accuracy a pre-requisite for device purchase. Also discussed was how IBIS model accuracy could be measured, such as passing a Golder Parser, measurement against lab verification metric, etc. There was a good amount of discussion regarding what the lab verification metric should be. One of the comments made was that different circumstances warrant different grading of the models and that the conditions of the grading must be clearly communicated. Greg suggested three levels of accuracy - 1) Corner silicon vs. IBIS corner simulation, 2) Typical silicon vs. typical IBIS; SPICE corners vs. IBIS corners, and 3) Typical silicon vs. typical IBIS; best guess corners. Although no conclusion was reached there was discussion regarding what type of supporting documentation should be supplied with the models. Lastly, test procedures were discussed such as IV curves, capacitance measurements and waveforms for representative test loads. If you would like copies of Greg's slides, please send Kathy Breda (just reply to this note) your postal address and a copy will be mailed to you. Discussion Topic 2: ------------------- The meeting than moved on to the creation of smaller working groups. To keep momentum and progress, there is a need to create smaller working groups that will meet between meetings and report back on their discussions. We also want to make sure we coordinate with the Open IBIS forum. Ed Sayre of NESA will be the main interface for the IBIS User Group meeting here on the East Coast. Two sub-committees were formed: 1) IBIS model validation/accuracy - how to construct a standard for valid models useful in system applications, how they are simulated under different loading and termination conditions, etc. headed by Greg Edlund, DEC. (greg.edlund@digital.com) 2) Software aspects of IBIS as it affects the user community - IBIS to SPICE, SPICE to IBIS, syntax and documentation, materials for education & Standardization, etc. headed by Paul Galloway, Cadence Design (pgjr@cadence.com) January Meeting: --------------- Next meeting is planned for Thursday, January 15, 1998 at 3:00 P.M. Tentatively scheduled to be held at Stratus Computer, Marlboro, MA. A formal agenda will be published after the holidays, however, the general plan is to have each of the sub-committees provide a report on their status and also have a guest speaker.

We, Applied Simulation Technology have supported IBIS from its inseption in 1989 or so. We are an SI SPICE vendor. We have an IBIS translator that converts IBIS formated parsed data into SPICE behavioral models. So once its in IBIS the model is a push button away. I am also aware that other Spice vendors support IBIS as well. So I think your a bit off base. Since your a member of the IBIS commitee and we attend the same meetings I'm a bit surprised of your apparent lack of knowledge along those lines. Anyway your statement about Spice vendors not supporting IBIS is quite incorrect. You can check out our stuff on the web. I suggest that may want to do that just for your information. -- Fred Balistreri fred@apsimtech.com http://www.apsimtech.com From owner-ibis Tue Dec 23 14:34:15 1997 Received: from gatekeeper2.nsc.com (natsemi3-bh.nsc.com [205.227.60.66]) by server.vhdl.org (8.8.5/8.8.3) with SMTP id OAA15349 for ; Tue, 23 Dec 1997 14:34:15 -0800 (PST) Received: (from uucp@localhost) by gatekeeper2.nsc.com (8.6.12/8.6.11) id OAA10124; Tue, 23 Dec 1997 14:32:01 -0800 Received: from nsc.nsc.com by natsemi3-bh.nsc.com via smap (3.2) id xma010021; Tue, 23 Dec 97 14:31:49 -0800 Received: from lightning.nsc.com by nsc.nsc.com (5.65/1.34) with SMTP id AA19297 for sjpeters@ichips.intel.com; Tue, 23 Dec 97 14:31:48 -0800 Received: from kural by rockie.nsc.com (4.1/SMI-4.1) id AA17769; Tue, 23 Dec 97 14:33:56 PST Date: Tue, 23 Dec 97 14:33:56 PST From: huq@rockie.nsc.com (Syed Huq) Message-Id: <9712232233.AA17769@rockie.nsc.com> To: sjpeters@ichips.intel.com, fred@apsimtech.com Subject: Re: hspice behavioral model from ibis 2.1 Cc: jplunket@qntm.com, ibis_users@vhdl.org, ibis@eia.org, jackie_jackson@avanticorp.com Hi, AMPredictor from AMP is another tool that can convert IBIS-to-SPICE.

I don't know of any other comercially available IBIS to SPICE products. My suggestion would be to contact Avant! directly (and any other SPICE vendors you care to) and make your needs known. As an aside, this subject (IBIS to SPICE converter) has been discussed a number of times on the IBIS reflector. There is, I think, a demonstrated need for such a tool. It's too bad the SPICE vendors have (so far) not been willing to step up to the task -- I think they are missing a real opportunity to help the SI community do it's job, as well as promote there own products. Oh well...if we keep posting they perhaps they will see the light. 'nuff said. As usual, the opinions the expresed here are my own and do not necessarily reflect those of my employer.

I was refering specifically to support for IBIS version 2.1 -- specifically the V/T curves. I know that Avant! (then Metasoft) and Microsim did do IBIS to SPICE translators for IBIS v1.1, but either did not go onto 2.1 or dropped support for V/T curves. I was not aware of any other vendors that supported IBIS 2.1. If Applied Simualtion does then my appologies, and I stand (most happely) corrected.
