Intel Arria 10 User Manual

5.2.2.6.1. PRBS Checker
You can use Arria 10 pseudo-random bit stream (PRBS) checker to easily characterize
high-speed links without developing or fully implementing any upper layer of a
protocol stack. The PRBS checker in Arria 10 devices is a shared hardened block
between the Standard and Enhanced datapaths. Hence, there is only one set of control
signals and registers for this feature.
You can use the PRBS checker block to verify the pattern generated by the PRBS
generator. The PRBS checker can be configured for two widths of the PCS-PMA
interface: 10 bits and 64 bits. PRBS9 is available in both 10-bit and 64-bit PCS-PMA
widths. All other PRBS patterns are available in 64-bit PCS-PMA width only. The PRBS
checker patterns can only be used when the PCS-PMA interface width is configured to
10 bits or 64 bits.
The pseudo-random bit stream (PRBS) block verifies the pattern generated by the
PRBS generator. The verifier supports the 64-bit PCS-PMA interface. PRBS7 supports
64-bit width only. PRBS9 supports 10-bit PMA data width to allow testing at a lower
data rate.
