Webb28 jan. 2008 · Recovery time is the minimum length of time an asynchronous control signal (eg.preset) must be stable before the next active clock edge. The recovery slack time calculation is similar to the clock setup slack time calculation, but it applies asynchronous control signals. Removal Time WebbThe difference is in terminology. With $setup/$hold, the clock is the reference event and data cannot change inside of a time window around the reference. With $removal/$recovery, the set/reset is the reference event and the clock cannot change inside of a time window around the reference. WebbStatic Timing analysis checks every path in the design for timing violations without checking the functionality of the design. This way, one can do timing and functional analysis same time but separately. This is faster than dynamic timing simulation because there is no need to generate any kind of test vectors. sprayplanet customer service
