This group has been very quiet for the past year.  There are some
interesting issues in vlsi that bear discussion.  Of course if no one
wants to discuss them then ... .   Anyway does anyone want to bradcast
an opinion on the issue of self timed vs synchronous hardware?  My
personal bias is towards synchronous hardware.  I have designed and
participated in the design of several synchronous systems but not
self timed so I am more comfortable and find it easier to reason about
synchronous hardware.  Self timed hardware is faster than synchronous
hardware (potentially) but requires more hardware to implement.  Also
I think feedback should create problems in a self timed system that do
not exist for synchronous systems.  Any partisans for either side?
