WebbThe compressor outputs drives combinations of compressed scan chains, combined using XOR logic. An fault from a compressed scan chain results in a specific incorrect values at the compressor outputs. The compressor input are the scan chains. As the compressed scan chain count increases, more XOR configurations are needed. If Webb17 feb. 2000 · This example includes two scan chains, one for each clock domain. The first scan chain starts with scan input 1 going through flip-flops 1 and 2 to scan output 1. The second scan chain starts with scan input 2 going through flip-flops 3, 4, and 5 to scan output 2. The circuit has only one scan-enable signal, even though there are two scan …
