Hi King22,


So, to make it simpler, this is what we got from your explanation as below. Can you help to see each one of the scenarios and confirm if it is accurate or not?


- 21.1, fpll's source = iopll, >4 transceiver channels - crash with internal error


- 21.1, fpll's source = iopll, =<4 transceiver channels - can compile, fpll can lock


- 22.4, fpll's source = differential clk, >4 transceiver channels - can compile, fpll can lock


- 22.4, fpll's source = iopll, >4 transceiver channels - can compile, fpll cannot lock


- 22.4, fpll's source = differential clk, =<4 transceiver channels - can compile, fpll can lock


- 22.4, fpll's source = iopll, =<4 transceiver channels - can compile, fpll cannot lock
