Orthogonal scan paths, which follow the path of the data flow, can be used in data path designs to reduce the test overhead -- area, delay and test application time -- by sharing ...
Scan compression has emerged as the most successful solution to solve the problem of rising manufacturing test cost. Compression technology is not hierarchical in nature. Hierarch...
—We present a dictionary-based test data compression approach for reducing test data volume and testing time in SOCs. The proposed method is based on the use of a small number of...
1 The increasing test data volume needed to test core-based System-on-Chip contributes to long test application times (TAT) and huge automatic test equipment (ATE) memory requireme...

—Conventional scan design imposes considerable area and delay overheads. To establish a scan chain in the test mode, multiplexers at the inputs of flip-flops and scan wires are...
