Hi @SyafieqS

ps2_host is an IP core intended to be instantiated rather than used as the top level - but you can work around this by setting the generic value as follows in Quartus: Assignments - Settings - Compiler Settings - Default Parameters; then create and add a parameter named fclk with a value of 1.0.
