13.2 EDK - Virtex-5FX FPU does not meet 200 MHz timing in High Speed Mode


If I enable the PowerPC's floating point unit in high-speed mode at 200 MHz, it does not meet timing. The FPU datasheet states that a FX130T-1 should be able to run the FPU at 200 MHz in this mode.


Currently, the only work-around for this issue is to run the FPU at a lower clock rate.

There are no plans to fix this issue at this time.
