I try to instantiate an RS232 UART Intel FPGA IP. and it gives the following error during generation:

Error: rs232_0: The input clock frequency must be known at generation time.

I tried the workarounds available in Intel resources, Both Intel IP catalog or Platform designer does not work. Platform designer has clock source instantiated and clock frequency set properly.
