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.

WebOct 17, 2010 · A master clock is a clock defined using the create_clock specification. When a new clock is generated in a design that is based on a master clock, the new clock can be defined as a generated clock. For example, if there is a divide-by-3 circuitry for a clock, one would define a generated clock definition at the output of this circuitry. bilyt genericoWebExclusive clocks are not active at the same time (e.g, multiplexed clocks).
