Document Table of Contents PRP Verifier

The PRP verifier is available in Stratix V devices for the 10GBASE-R protocol mode. The PRP verifier monitors the output of the descrambler when block synchronization is achieved. You can enable this block for custom 10GBASE-R configurations. The PRP verifier:

  • Searches for a test pattern (two local faults, or all 0's) or its inverse
  • Tracks the number of mismatches with a 16-bit error counter

Note: You can enable either the PRP verifier or the PRBS verifier, but you cannot enable both at the same time.
