•-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.
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

Note
Making number smaller may produce less compressed test sets.
