Minutes of the VASASG in Irvine CA 6/12/92
		Meeting #4
		Mark Brown
Overview:

The meeting was held at the University of California, Irvine on 6/12/92.
A list of the members in attendance is attached to this document as well as a
white paper written by Kevin Nolan and a complete list of the requirements
that were submitted to the Requirements Analysis group. The goals of this
meeting were to review the requirements analysis work thus far, to continue
the analysis discussions and to develop new work items for the next meeting.


General Discussions:

The agenda for this meeting was as follows:
	* Review work accomplished at the Santander Spain meeting.
	* Discuss white paper written by Kevin Nolan.
	* Continue review of the draft Design Objectives document.
	* Review and update the work schedule.
	* Develop new work items for the next meeting.


Santander Meeting Summary:

Kevin Nolan gave a brief summary of the Santander Spain meeting. The
following are the highlights:
	* Dominique Rodriguez presented the first draft of the Design
           Objectives (DO) document.
	* Kevin Nolan presented a top-down design methodology using
           a control system paradigm. This kind of design methodology 
           is required by various users.
	* Began detailed analysis of the draft DO document.
		+ General agreements reached:
			- Generalize operational semantics to more than just
 			   electrical. Allow representation of other physical
 			   systems such as thermal and mechanical.
			- Language will NOT standardize implementation
 			   algorithms.
	* Kevin Nolan agreed to write a white paper on various issues.
	* Robert Cottrell agreed to update the DO document and return
 	   the master copy to Hazem El-Tahawy to manage.
	* Further discussion will be by email, using the mailing list set
 	   up by Robert Cottrell. The address of the mailing list is:
			dr1076_1@lsi-logic.co.uk
				or
			dr1076_1@lonfs01.lsil.com
	   Anyone wanting their name added to or deleted from the list
 	   should contact Robert Cottrell at:

	   Model.
	* Interaction between the Discrete and Continuous Time	Domains.
2. Dave Barton agreed to write a glossary of terms.
