IEEE Std 1076.1.1 Working Group - Standard VHDL analog and mixed-signal extensions - packages for multiple energy domain support Meeting Minutes Date : 6th March 2003 Location : DATE 2003, Munich, Germany Attendees ------------ Peter Wilson prw@ecs.soton.ac.uk Alain Vachoux alain.vachoux@epfl.ch Tom Kazmierski tjk@ecs.soton.ac.uk Christophe Grimm grimm@informatik.uni-frankfurt.de Juergen Pfitzenmaier pfitzen@pfitzenmaier.de Michael Seibt mseibt@synopsis.com Roger Holden roger.holden@nokia.com Marius Sida marius_sida@mentor.com John Shields john.shields@synopsis.com John Willis jwillis@ftlsys.com (Note: this meeting was held in conjunction with the IEEE Std 1076.1 WG Meeting) Introduction and Update ======================= PW gave an update of the current status of the packages, highlighting the particular changes since the last meeting (FDL 2002). Some discussion followed the review of the packages as detailed below: Fundamental Constants ===================== This package was seen as in good shape. AV noted the aliasing of DECA and DEKA in the scaling constants. Material Constants ================== There was some discussion about this package, particularly with reference to the role of deferred constants. The definition of ambient_temperature provoked some discussion about the use of temperature variables,but in the end there was consensus that it remained in the package. Electrical_Systems ================== PW proposed the addition of flux_density and field_strength (B & H in magnetic systems) and there was no opposition to this. The change of the units from A-t (Ampere turns) to A for MMF was discussed, with the consensus that this was sensible.JW noted that it would be worth checking the IEC definition as well as the NIST definitions & offered to provide PW with the appropriate references. Action: PW to check the IEC definition of MMF units Radiant_Systems =============== PW presented the revised radiant_systems package, with updated names and units. AV and MS recommended experts who could take a look in addition to the reviewers already looking at the revised package. Action: PW to continue seeking reviews specifically for this package Mechanical_systems ================== PW presented the mechanical systems package, and some light was shed on the compliance type. JW & MS provided input for the correct units & symbol - PW to check. Action: PW to check correct symbol and unit for compliance Thermal_systems =============== PW requested input on the thermal systems package fluidic_systems =============== PW requested input on the fluidic systems package from the micro- and bio- fluidics perspectives - some suggestions were made - PW to check them out. Action: PW to obtain input from Bio-&Micro-Fluidics contacts at UoS General Issues ============== AV noted that as the packages were becoming fairly stable, that a revision of the packages should be posted to the web, with a time deadline for review, and then to being the balloting process. Action: PW to arrange this with AM (Professor Alan Mantooth, Group Chair) JW wondered if the packages as a whole could be marked with a clear revision number. PW noted that this could take place as part of the final revision process. Action: PW to set up a pre-ballot revision of the packages. JW raised the issue of dimensional analysis, and noted that as the unit & symbol attributes were now in the standard packages, that they could form the basis of a mechanism for dimensional analysis. Further discussion took place on this topic within the overall 1076.1 context. JW congratulated the WG on the standard packages and noted that his customers were also happy with the packages and they way tyey were heading. Next Meeting ============ Next meeting was proposed to be at DAC 2003 (June) in conjunction with the 1076.1 WG meeting
