Abstract

The art has addressed the problem of testing an embedded array [1] and of testing both logic and embedded arrays [2] where the design conformed with LSSD (Level Sensitive Scan Design) rules [3]. The problems of testing (i) unconstrained logic containing embedded arrays and (ii) static logic containing dynamic embedded arrays have not been addressed earlier and are solved by this article. This article encompasses the technique of (1] to test an embedded array and also provides a mechanism to test the containing logic without accessing the array.
