5.2.1.5.2. Pseudo-Random Pattern Generator

The pseudo-random pattern (PRP) generator is specifically designed for the 10GBASE-R and 1588 protocols. The PRP generator block operates in conjunction with the scrambler to generate pseudo-random patterns for the TX and RX tests in the 10G Ethernet mode. You can use the Arria 10 Pseudo Random Pattern (PRP) generator in the scrambler to generate random data pattern and seed that the scrambler can use. The 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. PRP is only available when the scrambler is enabled.

Refer to the Reconfiguration Interface and Dynamic Reconfiguration chapter for configuration details.
