Document Table of Contents Alternate Checkerboard Checker

The alternate checkerboard checker is implemented in the same way as in the alternate checkerboard generator. To do a comparison, an initial seed internally generates a set of expected data pattern result to XOR'ed with the input data. The seed is updated only when the enable signal is active, which indicates that the input data is valid. The checker flags an error when it finds any single mismatch between the expected data and input data.
