How to control fan out of an asynchrounous signal

Hi, We had a design let say would be replicated more than 8000 times or would generate 8000 of fan-out for the reset signal. Module:process(reset,clock) Begin If (reset=’1’) then S...

Please excuse my penetrant asking, it wasn't actually clear to me. I think, it's not mainly a fanout problem rather than of achieving the correct timing for the reset signal along the clock path at a rather high clock frequency. Avoiding asynchronous controls for fast registers simplifies timing closure a lot. Do you really need an asynchronous reset?
