Insert Testability
Tools Supported: FastScan
Scope: Atpg, Fault, and Good modes
Usage
INSert TEstability [-Control_max integer] [-Observe_max integer]
Description
Performs testability analysis to achieve maximum test coverage.
The Insert Testability command performs a complete testability analysis with
automatic ‘soft’ circuit modification to achieve maximum test coverage with a
maximum number of inserted control and observe points. The tool also determines
test coverage using the number of patterns you specify with the Set Random
Patterns command.
This analysis uses existing circuit modifications to determine the test coverage.
You can display all the circuit modifications by using the Report Control Points
and Report Observe Points commands.
You use this command primarily for simulating Built-In Self Test (BIST)
circuitry.
Arguments
• -Control_max integer
An optional switch and integer pair that specifies the maximum number of
control connections that the analysis allows during the testability insertion. The
default value is 100.
• -Observe_max integer
An optional switch and integer pair that specifies the maximum number of
observe connections that the analysis allows during the testability insertion.
The default value is 100.
