The goal of ‘Scan Insertion’ is to make a difficult-to-test sequential circuit behave (during testing process) like an easier-to-test combinational circuit. Achieving this goal involves two steps – 1. Converting Regular Flop to Scan Flop All the flops in the design are converted into sc...
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...

To establish a scan chain in the test mode, multiplexers at the inputs of flip-flops and scan wires are added to the actual design. We propose a low-overhead scan design methodology that employs a new test-point insertion technique. Unlike the conventional test-point insertion, where test ...

PROBLEM TO BE SOLVED: To reduce time for scan inserting processing in designing. ;SOLUTION: In the case of executing logical designing from a low-ordered logical block to a high-ordered logical block, scan insertion to a non-scan circuit is executed first to prepare a data record indicating ...
The diagnosis of faults to replaceable units at the system or board level can be enhanced by selective insertion of serial scan shift registers as test points within or between the replaceable units. A systematic approach to the selection of locations for such test points in order to realize a...
