Right now only the simple dV/dT numbers are accesible from the Converter for the resulting SPICE model. I assume that the tables are there because a simple slew rate limiting model is not sufficient. It seems that this is a two part problem. 1) What should the converter do with the V/T table data and 2) how can a SPICE model use the data to implement the characteristic. Is there any information anyone can provide me with that details how the V/T table could be implemented in a SPICE model? Please note that I have asked this question of a few people and the answer I get is that it is posible using proprietary SPICE model primitives. It seems to me the end users would benefit greatly from a SPICE-like topology and primitive model set that handles the V/T table feature of IBIS. BTW There exists a public domain standard for adding C code subroutines to SPICE as new model primitives. Its called XSPICE and its used by 7 different SPICE vendors. C source code done in XSPICE will run on these seven vendors SPICE programs and anyone else who adopts XSPICE extensions to SPICE. XSPICE is from the Georgia Institute of Technology and is freely available. XSPICE already has an extended SPICE primitive set including 40 extra SPICE primtives like slew rate limiter, table model, laplace model, VCOs, etc. Is there anyone out there who can supply the subcircuit topology and description of the required new SPICE primitives? We would gladly add this capability to the free converter. Charles Hymowitz - V.P. Prod. Dev.

I want to describe a package with single line descriptions in the [Pin Numbers] section like this: [Pin Numbers] | 20 Len=0 R=0.01 L=2.0n / Len=1.5 L=0.17n C=0.2p / Len=0 L=1.5n / ... This method adequately describes the package trace, so I don't want to use the [Model Data] section with it's required matrices. Theoretically and practically, this should work. According the the IBIS 3.0 this is not legal, and the ibischk3 reports errors. Why is this syntax allowed if we still have to define [Model Data] and the matrices? How can I fake it out, to just use my one line descriptions?

I will take a quick shot at this. s2ibis is a North Carolina State generated shareware that translates an SPICE model into IBIS hence the name. IBIS models are basically I/O Buffer information specification that contains V/I, V/T and various types of data describing the turn on/off of the buffer stages of most digital IC's(plus more). These models are not like a typical SPICE model. Your best bet would be to go to the IBIS website at http://www.eia.org/eig/ibis/ibis.htm and read up on various helpful information. Visit the Articles, FAQ, FREE Tools, Specs, Support sections etc Best Regards, Syed Cisco Systems, Inc. > > Hi, > I have recently joined IBIS work. I have a few querries.Could you please tell me what is s2ibis , what it does. What are IBIS models.Are they in soice ?

When the [Package Model] was introduced, in Bird 10.2, it probably made sense to require [Model Data]. Without [Model Data], there would have been little value in using a package model. However, now (BIRDS 28.3 and 37.3, included in IBIS 3.0 and beyond) a package model may have transmission line models for pins using sub-parameters Len, L, R, C, Fork, and Endfork. This provides another reason to use a package model. Yet the IBIS specification still requires [Model Data], which requires at least a [Capacitance Matrix] and an [Inductance Matrix], even if no coupling data is provided. Question: does it still make sense to require [Model Data] in a package model? *********************************************************************** * Geoffrey Ellis * * Cadence Design Systems phone: 831-685-6559 * * 9057 Soquel Drive fax: 831-685-6556 * * Aptos, CA 95003 E-mail: geoff@cadence.com * *********************************************************************** From owner-ibis Wed Oct 21 19:21:07 1998 Received: from mitac.mic.com.tw ([203.66.161.1]) by server.eda.org (8.8.5/8.8.3) with SMTP id TAA27044 for ; Wed, 21 Oct 1998 19:21:01 -0700 (PDT) From: martin.shih_at_tpe@smtplink.mic.com.tw Received: from smtplink.mic.com.tw by mitac.mic.com.tw (SMI-8.6/SMI-SVR4) id KAA13014; Thu, 22 Oct 1998 10:16:04 +0800 Received: from ccMail by smtplink.mic.com.tw (ccMail Link to SMTP R6.00.02) id AA909076529; Thu, 22 Oct 98 10:15:37 +0800 Message-Id: <9810229090.AA909076529@smtplink.mic.com.tw> X-Mailer: ccMail Link to SMTP R6.00.02 Date: Thu, 22 Oct 98 10:14:40 +0800 To: Subject: unsubsribe MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit unsubsribe -- Best Regards, Martin Shih ========================================================================== * Vincent Chang * * Design Automation mailto:vchang@micron.com * * Memory Products Design http://www.memh.ti.com/~mcad * * Micron Technology Inc.

Geoffrey: Your desired interpretation is correct. Pending BIRD54 is issued to correct a mistake in the document, and a related BUG32 is issued to correct a corresponding mistake in the ibischk3 parser in this area. The intention of the authors was NOT to require the [Model Data] and corresponding matrix formulations when using the transmission line format for package models. This should be resolved at the next meeting.

The strength has nothing to do with speed. There is no way to imply any goodness or badness in a model by some kind of correlation between speed and current. Strength helps keep speed up into high capacitive loads, more current is available to charge the cap.

In general these parameters are passed thru to the simulator so that the simulator can calculate the difference in "time to Vmeas" between the test load and the actual load. This number is then used in figuring the flight time of an interconnect. The actual propagation delay is not included because it does not effect the actual SI simulation waveforms or interconnect timing. Regards, Stephen Peters Intel Corp.
