WebMar 11, 2015 · Drill in to the Inter-Clock Paths entry. You’ll see there are hold time violations on signals passing from the clk_fpga_0 clock to the clk clock domain. In my design, there are seven failing paths and the total hold slack is -12.838ns. If you click on the red Hold line, you’ll see the seven
