Webcreate_clock ¶ Creates a netlist or virtual clock. Assigns a desired period (in nanoseconds) and waveform to one or more clocks in the netlist (if the –name option is omitted) or to a single virtual clock (used to constrain input and outputs to a clock external to the design). WebMar 4, 2024 · The clock generator is reset by Xillybus' "quiesce" signal, so bus_clk is guaranteed to be stable when it goes out of reset. Note that using bus_clk as the reference for icap_clk will make Vivado consider them as related, and unnecessarily apply timing constraints to paths between these two.
