WebOct 7, 2024 · Its clock attributes include A, that is, the automatically generated clock, that is, these clocks are not the clocks that we manually constrain in the Xdc file, but the clocks that are automatically constrained by the IP core according to user-defined settings. WebExclusive clocks are not active at the same time (e.g, multiplexed clocks). The mutual exclusivity must be declared to the Timing Analyzer to prevent it from analyzing these clock interactions. You can use the set_clock_groups command to specify clocks that are exclusive or asynchronous.
