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
