Mentor v8.6_4 manual Set Multiple Load

Command Dictionary Set Multiple Load

Set Multiple Load

Tools supported: Fastscan

Scope: All modes

Usage

SET MUltiple Load ON OFf

Description

Specifies how the tool handles multiple scan loads.

The Set Multiple Load command specifies how the tool handles multiple scan loads. It supports patterns containing more than one scan load operation. You can use this command to take advantage of non-scan sequential cells which are capable of retaining state through a scan load operation. The multiple load functionality is an extension to clock sequential ATPG.

When multiple load patterns are in the pattern set, an additional line is output in the statistics report. This extra line indicates the number of multiple load patterns in the current pattern set. For example:
