Arguments
•
-Max_measures number
An optional switch and integer pair that specifies the maximum number of
patterns (cycles) with an IDDQ measure statement that the tool allows in the
final set. Once the command identifies the maximum number of IDDQ
measurements, the command terminates. The default is all patterns with an
IDDQ measure statement.

•
-Threshold number
An optional switch and integer pair that specifies the minimum number of
IDDQ faults an IDDQ measurement must detect to pass the selection process.
The default is 1.

The default is 1.
•
-TEst_coverage [integer] (FlexTest only)
An optional switch which sets the iddq selection process to stop when the

•
-Eliminate
An optional switch that, for FastScan, deletes all patterns from the internal
pattern set that do not contain an IDDQ measure statement. For FlexTest, this
option removes only the cycles that follow the last cycle having an IDDQ
measure statement. This is the default.
