Document Table of Contents Parallel PRBS Checker

The PRBS checker contains the same polynomial as in the PRBS generator. The polynomial is only updated when the enable signal is active, which indicates that the input data is valid. The feedback path is XOR'ed with the input data to do a comparison. The checker flags an error when it finds any single mismatch between polynomial data and input data.
