Set Checkpoint
Tools Supported: FastScan and FlexTest
Scope: All modes
Prerequisites: You must use the Setup Checkpoint command prior to this
command.
Usage
SET CHeckpoint OFf | ON
Description
Specifies whether the tool uses the checkpoint functionality.
The Set Checkpoint command determines whether the tool uses the checkpoint
functionality that you specified with the Setup Checkpoint command. At tool
invocation, the checkpoint functionality is off, which means that during ATPG,
the tool does not save patterns into the file that you specified with the Setup
Checkpoint command. The tool only retains the internal patterns at the end of the
ATPG run.
If you set the checkpoint functionality on, then during ATPG, the tool saves the
patterns into the checkpoint file at the end of each time period specified by the
Setup Checkpoint command.
Arguments
• OFf
A literal that specifies for the tool not to use the checkpoint functionality
during test pattern generation. Patterns are not written to any file. This is the
default behavior of the tool upon invocation.
• ON
A literal that specifies for the tool to use the checkpoint functionality. The tool
writes test patterns that it generates to the file that you specified with the Setup
Checkpoint command.
