Tom,
You're right of course (must have been Holiday senility on my part). Having
access to a common model (Verrilog, VHDL, or some such) for the ASIC would be
a real plus. Actually, a bus transactor model would be a win as well. It would
certainly tend to cut down on the issues of platform compatibility that seem
to plauge a lot of the third party option world. Given a reasonably thorough
model, there should be a lot less chance of having an option card work on one
system platform and not on another one (I don't expect there to be any absolute
solutions to this problem of course; I'm idealistic, not foolish ;-) and there
are simply too many folks who will choose not to verify their designs).
So add such a model to my list of items that should be supplied for this new
interconnect.
Still just my own 2 cents (which will hopefully be worth more in a 93 economy).
Thanx,
AJ
