LAMP: System Description

The explosive evolution of digital devices, computers, and systems since the invention of the transistor has necessitated a parallel industrywide development of tools for the design and test of logic circuits. Whereas the oscilloscope was the mainstay of the digital circuit designer in the early days of discrete-transistor logic circuits, it soon proved to be inadequate for design verification and fault-behavior testing of large systems employing integrated, digital logic. In response to this need for better logic-circuit-development tools, a host of digitalsimulator algorithms and simulator systems has been produced. 1-3 1431 The need for reliable and dependable electronic switching systems (ESS) poses critical design problems. Computer-aided techniques can be used effectively for: (i) (m) (in) (·iv) (v) (vi) Analysis and enhancement of system diagnosability. Logic-design verification. Generation of fault-detection tests. Analysis of faulty-circuit behavior. Verification and evaluation of diagnostic-test designs. Production of trouble-location manuals (TLMs). ·y
