Aspects on integration of high-speed multiplexers and demultiplexers in VLSI test systems

Abstract

The authors describe hardware and software solutions for the design of a high-speed tester channel. Using gallium-arsenide circuitry for the merging of tester pin waveforms, cycle periods of less than 1 ns have been achieved. Hardware design alternatives are discussed, and a scheme for the automatic generation of tester-readable pattern description files is introduced. The conversion algorithms that allow for this generation are described.<>
