Patent DE-2349324-A1 (DE)
Inventor: EICHELBERGER EDWARD BAXTER
IPC: H03K3/037
Filed: 1973-10-01
Abstract: Level sensitive testing is performed on a generalized and modular logic system that is utilized as an arithmetic/logical unit in a digital computer. Each arithmetic/logical unit of a computer is formed of arrangements of combinational logic networks and storage circuitry. The storage circuitry has the capability for performing scan-in/scan-out operations independently of the system input/output and controls. Using this scan capability, the method of the invention provides for the state of the storage circuitry to be preconditioned and independent of its prior history. Test patterns from an automatic test generator are cycled through the networks of combinational logic and their respective associated storage circuitry for removal through the scan arrangement to determine their fault status.
