WebMay 29, 2016 · You don't need a derived clock here and you should always avoid using derived clocks if you can. Derived clocks are not synchronous design and so can cause big problems unless you know what you're doing. So, don't clock your second always block with slow_clk [N-1], clock it with clk and use slow_clk [N-1] as an enable signal. Don't do … WebThe derive_pll_clocks command prints an Info message to show each generated clock the command creates. As an alternative to derive_pll_clocks you can copy-and-paste each create_generated_clock assignment into the .sdc file. However, if you subsequently modify the PLL setting, you must also change the generated clock constraint in the .sdc file.
