Abstract

Structural test can address only stuck-at faults unless some dynamic capability is included. The dynamic capability required starts with two-vectorlaunch-capture delay tests, but evolves rapidly toinclude gated clock bursts, perhaps synchronizedwith primary I/O's. This implies an at-speed structural test architecture which incorporates many ofthe capabilities of functional test systems.
