Abstract
There is provided an improve BIST frontend state machine and a method for micro-architectural implementation of the same which is achieved with a minimal amount of test logic circuitry. The state frontend machine includes a state controller responsive to clock signals, control signals, and output register signals for generating output state signals based upon a fixed number of states utilizing death logic so as to sequence through one of a plurality of sets of tests until completed or failed. A substantial savings of approximately 40% in the I.C. chip area was realized in comparison to the implementation by a conventional state machine.
