A Self-Test Approach For Testing Crosstalk Faults in AMBA Bus -Based SoC
Li Jie, Asic System · Journal of Circuits and Systems · 2003
Crosstalk effect on interconnects is becoming significant especially in System-on-a-Chip (SoC) architecture in which the length of bus is intensively increased and the operating frequency of the chip reaches the order of GHz by the law of Moor. Some kind of crosstalk fault models and self-test methods are developed. A new crosstalk self-test method using the Maximal Aggressor Fault (MAF) model is proposed in this paper. By means of this method the Crosstalk faults of address bus, data bus and control bus in a SoC chip can be tested. The result also show that the area overhead is also decreased drastically compared with other method.
