Abstract

Systems and methods disclosed herein provide for efficiently loading mask data to the mask register bits from the decompression network outputs of an ATPG system. The systems and methods also provide an elastic interface utilized between a tester and a decompressor network (e.g., sequential and combinational decompressors) in order to expand the number of input variables utilized during the loading of the mask data to the mask register bits.
