Hi Adam,


I tried to run the simulation using Quartus flow (nativelink) and seem there is synthesis issue as below

Error(19750): VHDL error at ps2_host.vhd(53): formal generic fclk has no actual or default value


Assuming you are running the design independently with Quartus and Questa, maybe you can try to use nativelink method and see if thats possible.
