In the test pattern file generated by Modus tool in stil format, I wish to know what are the test patterns assigned to the PI and PPI.
Example (from the stil file)-
//***************************************************************************//
// TEST SEQUENCE.............3 TYPE......................normal //
//***************************************************************************//
// Processing the Static: EVENT 1.2.1.2.2.1.1; Scan_Load; (no_overlap)
// Inserted the Scan Sequence: Scan_Preconditioning_Sequence
// Inserted the Static: EVENT Stim_PI;
Macro "TEST" {
"ALLPIs" = 1000000;
"ALLPOs" = XXX; }
// Inserted the Scan Sequence # 3; Scan_Sequence
Macro "SCAN_TM_1" {
"CR_1_TM_1" = 1001 \r8 0 ; }
// Processing the Static: EVENT 1.2.1.2.2.2.1; Stim_PI;
Macro "TEST" {
"ALLPIs" = 0101101;
"ALLPOs" = XXX; }
// Processing the Static: EVENT 1.2.1.2.2.3.1; Measure_PO;
"1.2.1.2.2.3":
Macro "TEST" {
"ALLPIs" = 0101101;
"ALLPOs" = LHH; }
// Processing the Static: EVENT 1.2.1.2.2.4.1; Scan_Unload; (no_overlap)
"1.2.1.2.2.4":
// Inserted the Scan Sequence: Scan_Preconditioning_Sequence
// Inserted the Static: EVENT Stim_PI;
Macro "TEST" {
"ALLPIs" = 1101101;
"ALLPOs" = XXX; }
// Inserted the Scan Sequence # 4; Scan_Sequence
Macro "SCAN_TM_1" {
"OR_1_TM_1" = HLLH \r8 L ; }
In the test patterns, can I generate patterns with don't care (without filling the don't care bits with 0 or 1)
