Hey, John,

We haven't done any real work with ECO Compiler but I have tried it on
a state machine block.  I was impressed.  I made a small change to the
state machine and recompiled resulting in quite a different circuit.
After running ECO Compiler, only 3 gates were different.  ECO Compiler
was also able to see if my modified RTL was functionally equivalent
and give me back the same circuit as my original.

I'd be interested in specific problems people have had with ECO Compiler
so that I'll know what to look out for.
