ID:176168 All differential I/O pins driven by fast PLL <name> must have same I/O standard

CAUSE: You assigned different differential I/O standards to the differential I/O pins driven by the specified fast PLL. However, all differential I/O pins driven by the specified fast PLL must have the same I/O standard.

ACTION: Modify the design so all differential I/O pins driven by specified fast PLL have the same differential I/O standard.
