WebWhat you should instead do, is target the actual register driving the signal. You can do this with something like (haven't checked): create_generated_clock ... {pdm_clk_div clk_out} Where in this case clk_out is the name of the register inside the ```pdm_clk_div` instance which is driving the clock net. If the above doesn't work, you can try ... WebThe Vivado-generated schematic below shows how I create a forwarded clock for an FPGA source-synchronous output interface. The following create_generated_clock constraint seems to work properly since the path report for the interface shows that all components in the above schematic have contributions to the clock path delay.
