Hi,
I just got an XC5VFX70T-FF1136 here on my desk, planning to put it on my self-designed board. I am just wondering what max. speed I can expect for my internal logic. The speed grade is -1 and I need to design logic running up to 582 MHz. Should I rather buy a speed grade -2 to be on the safe side or isn't that an issue?
Regards Saul
