- 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
