The detection of crosstalk faults based on the processor core in the SOC

有效地给出了一种新的基于软件自测试的串扰故障渐进式激励检测模型实现 ,这种基于软件自测试的检测方案是利用SOC中的处理器核的计算和处理能力来产生激励矢量 ,对串扰故障进行激励并对测试响应进行分析 .为了提高测试速度 ,还提出了一种对IP核透明化处理的测试结构 ,该测试结构在增加较少额外硬件开销的前提下 ,极大地减少了测试时间 .同时 ,这种改进的测试结构也满足串扰故障激励检测的实时、并行的要求 .

Based on the crosstalk faults of interconnects between IP cores in SOC,this paper presented an implementation method for the model by using the control and operation function of processor core in the SOC. The method for software implementation needed less hardware burden in comparison with the traditional implementation one based on the hardware. A new IP core framework to improve the detecting speed of crosstalk fault was presented. The improved IP core made the test finished in the real-time and parallel requirement.
