Abstract
Representative embodiments are generally directed to storing compressed test pattern data on an automated test equipment (ATE) device. In one embodiment, the test pattern data is compressed according to a linear feedback shift register (LFSR). The LFSR may possess a low probability of occurrence of linear dependencies associated with compression of stimulus patterns to enable relatively highly compacted patterns to be compressed. Additionally or alternatively, repeat-filled test pattern data is run length encoded using variable length code words to facilitate parallel decompression within the ATE device.
