2.4.1.2.1. Specifying I/O Interface Uncertainty
Virtual clocks are recommended for I/O constraints because they most accurately represent the clocking topology of the design. An additional benefit is that you can specify different uncertainty values on clocks that interface with external I/O ports and clocks that feed register-to-register paths inside the FPGA.
