timing constraint for clock mux and how to set output delay

WebOct 9, 2024 · Hello, In my project, I have two different clock domains: 1. The first domain use the "sys_clk" from 10[MHz] external oscillator.2. The second domain use the "pll_clk" (60[MHz]) that generated by PLL module from source of 100[MHz] external oscillator.It says that the setup time slack of pll_clk is negative, I see the worst-case timing paths, I found …
