我们提出了一种设计测试发电机电路(TGC)的方法,该方法将预先计算的测试集包含在其产生的模式中。我们的方法使用基于D-Compatibles属性的宽度压缩,这使我们可以比仅使用兼容和逆兼容的以前的方法更有效地编码。 TGC由一个计数器组成,该计数器会生成一组编码的测试模式,以及由简单的二进制解码器组成的解压缩电路,该解码器生成包含T/sub D/的最终序列。这些TGC适用于嵌入式电路电路的详细设计。我们通过提供ISCAS 85和ISCAS CAS 89基准电路的实验结果来证明我们的方法的有效性。
We present a method for designing test generator circuits (TGCs) that incorporate a precomputed test set to in the patterns they produce. Our method uses width compression based on the property of d-compatibles, which allows us to encode to more efficiently than previous methods that use only compatibles and inverse compatibles. The TGC consists of a counter, which generates a set of encoded test patterns, and a decompression circuit consisting of simple binary decoders that generate a final sequence containing T/sub D/. These TGCs are applicable to embedded-core circuits whose detailed designs are not available. We demonstrate the effectiveness of our approach by presenting experimental results for the ISCAS 85 and ISCAS CAS 89 benchmark circuits.
