An APL system for experimentation with spectral methods in fault detection
Eric Gullichsen · ACM SIGAPL APL Quote Quad · 1986
An ability to detect faults in digital circuitry is of increasing importance as a result of the current trend towards ever-greater levels of circuit complexity in VLSI design. This paper describes a system of APL routines that permits the interactive specification of combinational circuits and the discovery of spectra for lines of the (fault-free) circuits. The system can also simulate the spectral behavior of a specified circuit under the condition of "stuck-at" faults on any combination of circuit lines, or under the condition of some internal line considered as if it were another circuit input.
