Abstract: Along with more pre-designed and pre-verified cores are integrated into a single chip to construct an entire system, the test application time increases significantly. This paper presents a novel test scheduling solution, unlike previous techniques that take advantage of balanced scan chains of every single core, utilizing the balance of pairwise combined cores. Experimental results for two ITC '02 SOC benchmarks show that the pair balance-based test scheduling technique achieves less test time compared to the previous approaches.
