Side Read Operation

The side read operation is performed between 18.923 ms and 18.963 ms. The DQS agent sends data to the DQS driver with the side_readdata signal. Data validation is carried out in parallel, by comparing the side_readdata signal against the content of the check_fifo (data which was written out during the DQS write operation). If there is a mismatch, the software generates an error message.

The following figure shows the waveform for the side read operation.
