P&R speed higher than synthesis

Sep 13, 2005 1 Replies

Hi, I seem to be getting a higher P&R speed (I put a constraint on the only clk I have in the design) than that I got from synthesis. Sometimes by up to



10 MHz. Is that possible? I am using ISE 6.3 and targeting a Virtex 2
1000 -4.

Thank you Adrian


I have seen that too on occasion, usually the very next change to the code fixes it right away:-)
