Abstract
Systems and methods disclosed herein provide for generating extra variables for an ATPG system utilizing compressed test patterns in the event an ATPG process is presented with faults requiring a higher number of care-bits than can be supported efficiently by the current hardware. The systems and methods provide for a multi-stage decompressor network system with an embedded serializer-deserializer. The systems and methods use a XOR decompressor in a first stage and a serializer-deserializer in conjunction with a second XOR decompressor in a second stage.
