ABSTRACT:
A data analyzer for use in BIST circuitry has been provided. The data analyzer allows both comparison analysis and signature analysis to be performed on a circuit response data stream. The data analyzer includes a plurality of data registers which are serially-coupled and where each data register is capable of performing comparison analysis and signature analysis on one data bit of the circuit response data stream. This allows the circuit under test can be completely and thoroughly tested for faults.
