Abstract :
A rigorous mathematical analysis is presented to identify error conditions under which aliasing can occur for several common types of serial signature analyzers (SSAs) and parallel signature analyzers (PSAs). The PSAs are faster and require less hardware than the SSAs; however, for PSAs some double errors are a special cause of concern. Such aliasing errors are analyzed and it is shown that PSA pairs can be identified for which these errors are disjoint. Novel reconfigurable PSA designs are presented which use a two-signature scheme to detect all double errors
