1.6.1.6.3. Ramp Wave Checker

The ramp wave checker is implemented in the same way as in the ramp wave 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.
