Set Control Threshold
Tools Supported: FastScan
Scope: All modes
Usage
SET COntrol Threshold integer
Description
Specifies the controllability value for random pattern simulation.
The Set Control Threshold command specifies the minimum number of times a
gate must be at a zero or a one state during random pattern simulation for the tool
to consider it adequately controlled.
You use this command primarily for simulating Built-In Self Test (BIST)
circuitry.
Arguments
•integer
A required integer, greater than or equal to 0, that specifies the controllability
value. The default upon FastScan invocation is 4.
Examples
The following example sets the threshold number to determine the controllability
effects during random pattern simulation:
set system mode fault
set random patterns 612
set control threshold 2
analyze control
report control data
