Overview Vector space Unused Vectors Used Vectors ± Inputs have to be meaningful for better coverage. ± While using random vectors it is impossible to visit the whole vector space. ± Spectral coefficients give us links from one vector space to another space which could have vectors within close range that will be able to give better fault coverage. ± Spectral analysis helps concentrate only on the vectors that are relevant thus reduces the white noise . ± Most importantly sequential circuit tests are not random so this method helps as this co-relates the vectors to one another.
