Due to the increased speed in modern designs, testing for delay faults has become an important issue in the postproduction test of manufactured chips. A high fault coverage is nee...
We present an algorithm for identifyinga set of faults that do not have to be targeted by a sequential delay fault test generator. These faults either cannot independently aect th...

Recent research results have shown that the traditional structural testing for delay and crosstalk faults may result in over-testing due to the non-trivial number of such faults t...

- We propose a novel oscillation ring (OR) test architecture for testing interconnects in SoC. In addition to stuck-at and open faults, this scheme can detect delay faults and cr...

- Two methods to apply tests to detect delay faults in standard scan designs are used. One is called launch off capture and the other is called launch off shift. Launch off shift t...
A low overhead DFT technique, called clock-grouping, for delay testing of sequential synchronous circuits is presented. The proposed technique increases robust path delay fault co...
This paper describes test generation for delay faults caused by global process disturbances. The structural and spatial correlation between path delays is used to reduce the numbe...
Many Built-In Self Test pattern generators use Linear Feedback Shift Registers (LFSR) to generate test sequences. In this paper, we address the generation of deterministic pairs o...
This paper presents adaptive techniques for improving delay fault diagnosis. These techniques reduce the search space for direct probing which can save a lot of time during failur...
When testing delay faults on critical paths, conventional structural test patterns may be applied in functionally-unreachable states, leading to over-testing or under-testing of t...
