Cyclone V SOC. Compiling the GHRD takes an insane amount of time

Hello,

This is expected since you add HPS IP to your system, compilation might take long time.

Regarding the HPS pins, these pins are assigned from HPS IP in Platform Designer. They are needed to be exported to top-level, but no pin can be see as assigned, since they use dedicated Pins.

Timing wise, you might see that HPS pins are either clocks (need to define the clock only) or false path. In both cases, nothing will affect timing on HPS since this is Hard-core IP.

Thanks
