Witryna1 cze 2007 · Automatic test-program generation (ATPG) tools target these fault sites and cause a transition using any launch scan cell and capture results using any downstream scan cell. Using PLLs for accurate clocks A fundamental problem with at-speed scan testing is how to apply accurate clocking for the at-speed launch and capture pulses. WitrynaWavelet Automatic Spectral Pattern Generator (WASP) is an improvement over spectral algorithms for sequential ATPG. It uses wavelet heuristics to search space to reduce computation time and accelerate the compactor. It was put forward by Suresh kumar Devanathan from Rake Software and Michael Bushnell, Rutgers University.
