Abstract:SUMMARY This paper preeents a power-constrained test scheduling method for multi-clock domain SoCs that consist of cores operating at different clock frequencies during test. In the proposed method, we utilize virtual TAM to solve the frequency gaps between cores and the ATE. Moreover, we present a technique to reduce power consumption of cores during test while the test time of the cores remain the same or increase a little by using virtual TAM. Experimental results show the effectiveness of the proposed meth… Show more
