K.  Stevens, Computer Science Department, University of
Calgary,  (formerly  HP  Laboratories,  Palo Alto) will
speak   on  "Synthesis  of  Asynchronous  Finite  State
Machines".

TIME:                 10:30 a.m. - 11:30 a.m.

ROOM:                 DC 1304

ABSTRACT

A  tool  called MEAT has been designed to automatically
synthesize   transistor-   level   self-timed   control
circuits.  MEAT has been used to specify and synthesize
circuits  for  a  fully  self-timed  300,000 transistor
communication   coprocessor  called  the  Post  Office.
Designs  are  graphically  represented similar to Mealy
state  machines.  A  new limited form of multiple input
change  signalling  called  BURST-MODE  was introduced.
The primary goal of MEAT is to produce fast and compact
circuits.

The application and design of MEAT as an AFSM synthesis
tool  will  be  discussed,  as well as some experiences
using it to design the large Post Office chip.
