Flash bist 测试
Weblbist通常用于测试随机逻辑电路,一般采用一个伪随机测试图形生成器来产生输入测试图形,应用于器件内部机制;而采用多输入寄存器(misr)作为获得输出信号产生器。 WebJan 2, 2007 · For FLASH memories also we can generate bist controller I feel . You get the memory testing spec sheet from the Vendor .There specifically you need to look for the sequence of alogorithm's required & also the algorithm of each one ,if thats not available in the mentor's algorithm list .
