Mentor v8.6_4 manual ∙ -EXhaustive FlexTest only, ∙ -IncrementalFlexTest only

Command Dictionary Select Iddq Patterns

∙-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
