We assume a hybrid bist approach , where a test set is assembled , for each core , from pseudorandom test patterns that are generated online , and deterministic test patterns that are generated off - line and stored in the system 在混合的bist方法中,对于每个芯核的测试向量集由在线产生的伪随机测试向量以及离线产生并且存储于芯片上的确定型向量组成。
Since the chip has interior sram and it ' s difficult and slow to test sram exteriorly , in chapter four we use the technique of bist in design of testability of sram , which makes it possible to test the memory at normal working speed 由于片内有sram ,而sram的片外测试比较困难且速度较慢,所以文中第四章采用bist技术对sram进行了可测性设计,完成后可以用正常的工作速度对存储器进行测试。
In this paper we propose an iterative algorithm to find the optimal combination of pseudorandom and deterministic test sets of the whole system , consisting of multiple cores , under given memory constraints , so that the total test time is minimized 与此同时为了减少测试成本以及产品上市时间,测试时间必须被最小化。在混合的bist方法中,伪随机向量的长度是决定整个测试过程的行为的一个重要参数。
Bist is an efficient solution for the testing of soc . it is built up with prompting and responding circuits and these two parts are added to the circuit being tested so that the engineer need not consider the testing vector , for it ' s generated automatically 而内嵌自测试技术对于解决soc生产测试的问题非常有效,它将一个激励电路和响应电路中加到被测电路中,从而使测试人员不必再考虑测试向量的问题,因为它是自动生成的。
