Application of Deterministic Logic BIST on Industrial Circuits

Abstract

We present the application of a deterministic logic BIST scheme on state-of-the-art industrial circuits. Experimental results show that complete fault coverage can be achieved for industrial circuits up to 100K gates with 10,000 test patterns, at a total area cost for BIST hardware of typically 5%-15%. It is demonstrated that a trade-off is possible between test quality, test time, and silicon area for the BIST hardware. In contrast to BIST schemes based on test point insertion no modifications of the circuit under test are required, complete fault efficiency is guaranteed, and the impact on the design process is minimized
