Hi,
Unfortunatly, I can not drive a global buffer with this clock because the maximum delay I get when I go by the global buffer is 8 ns which is incompatible with the fact that data is synchronous to the falling edge of the 80 MHz clock. I believe I will try something else with a much faster clock but just if this information is available what is the maximum skew provided by the clock tree in a Virtex II ? The reason for my question is that I read in a previous post that is was below 100 ps but when I run the timing analyzer it seems it is more like 300 ps. Did I miss something ? If not is my 450 ps skew small enough to consider no extra effort necessary ?
Thanks,
J.F. Hasson
