SET CYCLE
Scope: Sets timing information
Usage
SET CYCLE integer
Description
Extends the
FlexTest commonly defines clock pin timing using a test cycle with two timeframes. In this case, the clock goes active sometime within timeframe 2 and goes inactive at the end of timeframe 2. The second clock transition coincides with the input pin forces in the next test cycle, because by default input pin forces occur at time 0 in the first timeframe. This sometimes creates timing violations, such as hold time violations in
You can avoid these types of violations by specifying a
Note that this timing file command is similar to the PERIOD statement that FastScan uses in its TIMEPLATE description.
Arguments
∙integer
The period you wish to set for the test cycle. You must specify a cycle time greater than or equal to the last force time in the cycle, to remain consistent with FlexTest internal simulation.
