23.7.2.2 Step 2: Configure the FPGA Fabric FIC Clocks
Instantiate a CCC macro and configure it to satisfy the FIC subsystem clock rules, as described above.
Typically a global output (GLx) must be associated with each of the FIC clocks must be associated and a frequency specified for each output matching the frequencies defined in the MSS_CCC configurator. Microchip recommends generating all the global outputs from a fabric PLL to ensure the phase alignment (as shown in the following figure).
Important: If two FIC subsystems have the same frequencies, one
fabric CCC global output is sufficient for clocking both the FIC subsystems.
