Abstract:
A method to increase automatic test pattern generation (ATPG) effectiveness and compression identifies instances of “majority gates” and modifies test generation to exploit their behavior so that fewer care bit are needed. This method can increase test coverage and reduce CPU time as previously aborted faults are now tested. The majority gate enhanced ATPG requires no hardware support and can be applied to any ATPG system.
