Abstract
A PBIST architecture is described. A data path circuit is configured for bit-to-associated bit comparisons of expected result data read from a tile with the expected result data read from result memory. The data path circuit is configured to write a first type of failure indication to first failure memory responsive to a data 0 being read from the result memory and a data 1 being read from the tile for a bit-to-associated bit comparison failure. The data path circuit is further configured to write a second type of failure indication to second failure memory responsive to a data 1 being read from the result memory and a data 0 being read from the tile for the bit-to-associated bit comparison.
