WebFeb 16, 2024 · Solution You can take advantage of virtual clocks, which represent the clock at the external device connected to the FPGA, to constrain this type of path. A basic XDC constraint for this type of set-up is shown below: # Create virtual clocks create_clock -period 10 -name virtclk # Set input and output delay WebConversely, if you choose to route it from the fabric back to a dedicated clock route (via a clock buffer), you will have large skews between your source clock and your generated clock. In almost all cases, it is best to avoid structures like what you are describing - at least for internal use.
