Abstract

In this paper, a novel hybrid built-in self-test (BIST)approach for system-on-a-chip (SOC) test using anembedded FPGA core is presented. The hybrid BISTcombining pseudorandom test with deterministic test canachieve not only complete fault coverage but also minimaltest cost by selecting the appropriate number ofpseudorandom patterns. Most importantly, theFPGA-based hybrid BIST has minimal hardware overhead,since after testing, the FPGA core can be reconfigured asnormal mission logic. Experimental results for ISCAS 89benchmarks and a platform FPGA chip have proven theefficiency of the proposed approach.
