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...
: Conventionally, path delay tests are derived in a delay-independent manner, which causes most faults to be robustly untestable. Many non-robust tests are found but, in practice, ...
Circular built-in self-test (BIST) is a "test per clock" scheme that offers many advantages compared with conventional BIST approaches in terms of low area overhead, simp...
- 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...
