ASIC (Application-Specific Integrated Circuit) testability, troubleshooting access and visibility of internal circuitry are the primary targets of test engineering analysis. The widely applied boundary-scan technique does not solve all problems connected with the PBA (Printed Board Assembly) manufacturing process. This paper presents an extension of the boundary-scan technique currently implemented to provide ASIC testability. The concept of Collateral ASIC Test (method and logic) implemented in a boundary-scan device is described as well as the test process standardization implied by this new approach to ASIC design and testing.
