SET MUltiple Load ON | OFf

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:
