Bob Haller took minutes, because Lynn was off line - Review of minutes for April 22, 2003 Minutes approved with no changes - Announcements EIA Call for Patent Disclosure No company declared a patent. Barry will present an IBIS Quality Committee update at Both IBIS Summits (same presentation) IBIS summit at DAC2003 - June 5, 2003 IBIS summit at DesignCon East - June 23, 2003 - AR Review AR - Bob Haller to insert relevant information from Timing reference load Parser Bug submitted to open forum by IQ Committee into Model_section document. DONE AR - Barry to contact Mike Labonte to inform him to attend in two weeks to help review Waveform processing document. DONE AR - Look at minutes to review previous IV curve checks for level 0.OPEN AR - Bob Ross to dig up Table of legal IV curve combinations (from old parser bug). Done AR - Bob Haller update and post IV curve document. DONE - Opens for new items No new open Items - Detailed Documentation review Barry and Bob H. continued to walk us through the IV_Curve document (IQ_4_3_iv_curve.txt) Bob reviewed the major changes since version 0.1 Added levels Added keywords Editorial changes Reviewed changes made up to Pullup curves. Continued through the entire document.Barry suggested, and no one objected for us to re-organize document by level (0,1,2) after capturing all of the checks. Agreed on wording of recommendation on how to handle excessive currents Need to settle on value. 1 amp may be to low for high powered FET's. AR - Kim to determine warning limits in parser for excessive currents. Discussed check for proper order of Min Typ Max IV curves. Agreed to add following wording; In most cases the current of Max curves should be greater than the current of Typical IV curves which should be greater than the current of Min curves in the active region (i.e. When the device is Not clamping). Discussed non-monotonic warnings, and the fact that some small percentage of devices really do exhibit non-monotonic behavior. IQ documentation is intended to improve overall quality of large percentage of models (95%). There will be exceptions. Important point is to document issues. Wording to add to documentation is "Any non-monotonic IV curves must be documented". Review IV voltage sweep limits for all of the Curves. Power clamp should be -vcc to +2Vcc , Vcc relative. Bob Ross commented that there can be issues not sweeping the clamp curves sweep over the entire range (defined by IBIS). We cannot change this for IQ documentation. It is permitted to extend the range of the clamps. Power and ground clamps may contain the effects of ON-die termination. And those effects should go in both curves. Item 13 tri-state current should be less than 1ua. Add wording, "you expect that or understand (and document) why". It is important how the points are distributed on the IV curve because of the 100 point limit. This is not presently discussed in the document. Next we need to discuss and capture Level 2 checks for IV curves. AR - Bob Haller update and post IV curve document. - Plans for next meeting Complete IV_Curves document Review of ramp_and_waveproc.doc - Schedule for next meeting May 20, 2003 9-10 AM EST (6-7 AM PST) Phone: 408-974-8478 or 800-249-5618 Meeting access: CONFERENCE SERVER 1, Conference ID: 54644 Meeting ended at 10:00 AM Eastern Time.
