Scan based at-speed transition fault testing of Motorola's microprocessors based on the PowerPC(tm) instruction set architecture requires broadside transition fault test patterns that have a specific launch and capture clocking sequence. We describe the concepts we developed and incorporated in the ATPG tool to support efficient generation of such test patterns to achieve high transition fault test coverage and for analysis of undetected transition faults. Using the enhanced ATPG tool, we generated 15,000 transition fault test patterns and achieved 76% test coverage for the MPC7400 microprocessor based on the PowerPC(tm) instruction set architecture that has 10.5million transistors and runs at 540 MHz.
