Method for maintaining bus integrity during testing

摘要

The integrity of a bus (16) may be maintained in a circuit (10) during testing by first scrutinizing the circuit to learn whether a potential conflict will ever exist on the bus for any combination of input values to the circuit. If no conflict will ever exist, then the bus is deemed a no-conflict bus, and nothing further need be done to that bus during testing. Should the bus be found to be a potential conflict bus, then a bus justification vector is generated for application to the circuit to maintain the integrity of the bus intact during testing.
