ABSTRACT
A system that includes self-test features must have facilities for generating test patterns and analyzing the resultant circuitresponse. This article surveys the structures that are used to implement these self-test functions. The various techniquesused to convert the system bistables into test scan paths are discussed. The addition of bistables associated with the I/Obonding pads so that the pads can be accessed via a scan path (external or boundary scan path) is described. Most designsuse linear-feedback shift registers for both test pattern generation and response analysis. The various linear-feedback shiftregister designs for pseudorandom or pseudoexhaustive input test pattern generation and for output response signature analysisare presented.
