This is due to its compactness, high compression rate and adoptability to circuits with multiple scan chains. As a space compression method, an XOR network is typically used to compress the output response [4]. Unknown values are often seen in the output response of a circuit during logic and fault simulation [17].

(ATPG-generated) test set to the circuit under test (CUT). Survey of Test Vector Compression Techniques Test data compression consists of test vector compression on the input side and response compaction on the output side. Test vector compression has been an active area of research, yielding a wide variety of techniques. This This paper proposes a cascaded multicasting scan (CMS) architecture with simple control logic and low hardware overhead for test data compression. Instead of specifying all the addresses of the scan chains that will receive the test data in each broadcast, CMS specifies only the address of the first scan chain using log2(n) control bits in each broadcast on an n-scan .and the IF output is a fixed amount of compression. Mini-Circuits specifies the typical RF input power at the 1-dB compression point, where conversion loss is 1 dB greater than it is at low RF power. Naturally, if an application allows a greater amount of compression, the acceptable RF input power would be higher. Two efficient output selection algorithms are presented to determine the desired output responses, one using a single counter operation for simpler test control and the other using more counter .
