Observation of path delay faults requires propagation of transitions in a circuit which is done by application of pair of patterns. This paper proposes a single input change test pattern generator (SIC- TPG) that creates SIC pairs and hence can be used for path delay fault detection. The same...
it is difficult to control the flop’s value through primary inputs and observe the captured response in primary outputs. To solve this issue we do ‘Scan Insertion’ during synthesis
Scan chain based test has been a common and useful method for testing VLSI designs due to its high controllability and observability. However scan chains h... G Sengar,D Mukhopadhayay,DR Chowdhury - International Conference on Advanced Computing & Communications 被引量: 30发表: 2007年 Efficient...

Launch-off-shift (LOS) method provides higher fault coverage and lower pattern count when compared to launch-off-capture (LOC) method. Investigations have proven that some faults can be detected using LOC but not LOS and vice-versa. In LOS, the second pa

Boundary scan, JTAG technology relies on using VLSI integrated circuits that have a boundary scan capability. As a result there is a need for standardisation across the electronics industry. In order to ensure this occurred, boundary scan was adopted by the Institute or Electrical and Electronics ...
