Abstract

This paper presents a reconfigurable matrix based built-in self-test processor (RMBITP) which makes use of both software commands and reconfiguration of the design under test (DUT). The RMBITP self-test algorithm is based on a new 3-dimensional (stages) output data compaction scheme for minimizing the probability of aliasing error, the BIST time, and the engineering development effort while limiting the percentage BIST overhead to 15% or less. To illustrate the concept, the built-in selftesting of large complex designs ranging from 1 to 5 million gates is presented.
