12.x EDK - How can I make Clock Wizard recognize clock ports on custom peripherals?

Description


I have created a custom peripheral with its own clock port. When I launch the Clock Wizard, the clock port of the peripheral is not shown in the Wizard GUI.
How can I make the clock port recognized by the Clock Wizard?

Solution


Clock Wizard checks the SIGIS keyword in the MPD file to identify the clock signals.
The clock port of the peripheral needs to be specified as a clock signal with keyword "SIGIS = Clk".
For example:
PORT Peri_Clk = "", DIR = I, SIGIS = Clk, ASSIGNMENT = REQUIRE
