Description

This item was taken from the IEEE Conference ' WOR-BIST: A Complete Test Solution for Designs Meeting Power, Area and Performance Requirements ' A complete Built-In Self-Test (BIST) solution based on word oriented Random Access Scan architecture (WOR-BIST), is proposed. Our WOR-BIST scheme reduces the test power consumption significantly due to reduced switching activity during scan operations. We also provide a greedy algorithm to reduce the test data volume and test application time. We performed logic simulation of the test vectors to show its impact on the average and peak power during testing. We implemented the scheme to demonstrate its impact on the chip area and timing performance. Application of our scheme to large ISCAS and ITC benchmark circuits shows that our scheme is superior in area, power and performance to the conventional multiple serial scan.
