6.16.2. Using Pseudo Random Pattern Mode

You can use the Cyclone® 10 GX Pseudo Random Pattern (PRP) generator and verifier in the scrambler and descrambler to generate random data pattern and seed that the scrambler can use. PRP mode is a test mode of the scrambler. Two seeds are available to seed the scrambler: all 0s or two local fault-ordered sets. The seed is used in the scrambler to produce the pattern. The r_tx_data_pat_sel is the data pattern that the scrambler scrambles. PRP is only available when the scrambler is enabled. The PRP verifier shares the rx_prbs_err error signal with PRBS. The error count can be read out from the corresponding registers.
