WebThe create_clockconstraint is associated with a specific clock in a sequential design and determines the maximum register-to-register delay in the design. The following is a description of command syntax for specifying a clock: 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.
