Command Dictionary Select Iddq Patterns
FastScan and FlexTest Reference Manual, V8.6_4 2-421
•-Noeliminate
An optional switch that retains all patterns in the pattern set. You can look for
the IDDQ measure statement to identify the patterns that the tool selected to
perform an IDDQ measurement.
•-EXhaustive (FlexTest only)
An optional switch that specifies for FlexTest to first simulate all test cycles
for all faults, and then perform the selection process to pick the ones that detect
the largest number of IDDQ faults. This is the default.
•-Incremental (FlexTest only)
An optional switch that specifies for FlexTest to simulate test cycles one at a
time, checking each time that the IDDQ measurement satisfies the -Threshold
and -Percentage requirements. If FlexTest qualifies the maximum number of
cycles containing an IDDQ measure statement, it stops the simulation process
at that point without simulating the remaining cycles.
Examples
The following example fault simulates an external IDDQ pattern file and selects
the ten patterns with IDDQ measure statements that most effectively detect IDDQ
faults:
set system mode atpg
set pattern source external pat_file
set fault type iddq
add faults -all
set iddq strobe -label
select iddq patterns -max_measures 10 -noeliminate
