Command Dictionary Set Atpg Compression

∙-SEq_merge_limit number

An optional switch and integer pair that specifies the maximum number of faults that the test pattern generator will successfully attempt to merge with the target fault pattern. The -Seq_merge_limit switch is used by the sequential compression algorithm only. It is primarily for IDDQ and Toggle faults. By making number smaller, the tool more quickly terminates early compression efforts and implements fault simulation sooner. The default is 5000.

Making number smaller may produce less compressed test sets.

Note

Examples

The following example specifies for FastScan to try to detect multiple faults through a single observe point with each single test pattern:

set system mode atpg add faults -all

set atpg compression on run
