Hello all,
i have a design finished a few month ago, that is working fine on a xc2s200-pq208, but when i port it to a xc3s400-tq144, it ain't work most of the time (depends on the synthesis process) even with lowest frequencies for a single clock and a given period constraint.
Now, i wonder, if this is due to wrong regulators. Are there any other good guys here, using those? (If yes, please, tell me Package and Size of Fpga too. :-)
much thanks in advance walther
