FreeLists / si-list / [SI-LIST] Re: IBIS Model for Freescale MC68302

[olaney@xxxxxxxx]

The value of simulation is that you can verify that you have designed
things properly, but it shouldn't drive the design itself.  If you don't
understand first principles and can't apply physical reasoning to the
details of your implementation, reliance on simulation is a lapse into
the empirical and misuse of the tool.  12 MHz designs were hot stuff 25
years ago, long before anything like IBIS.  For this 68k design, generic
good SI practice should get you everything you want, unless you have a
profound talent for messing things up.  If you have the confidence and
knowledge, I say charge ahead.   Sure, I'd be tempted to simulate if I
was working with time deltas like 83 picoseconds, but here we are talking
about 83 huge, excruciatingly slow nanoseconds.  With the lasers at
certain research facilities, you could brew a cup of coffee in that much
time.
