2.3.1.3. Data Pattern Generator and Verifier

The PMA supports a built-in PRBS data pattern generator and verifier.
You can use the built-in PRBS generator and verifier patterns to perform design for test checks by generating the PHY data traffic. This feature allows you to debug the PMA without needing the upper protocol hard IP layers. The pattern and size are programmable. The supported programmable PRBS patterns are shown below:
  • PRBS31
  • PRBS23
  • PRBS15
  • PRBS13
  • PRBS10
  • PRBS9
  • PRBS7
The data pattern verifier contains a receiver built-in self test (BIST) bit error checker. The receiver can check standard data patterns for link verification applications by enabling the PRBS mode in both the receiver link and a compatible transmitter link connected by a common transmission path or loopback.
Note: The current release of the Quartus® Prime Pro Edition software does not support the built-in PRBS generator and verifier in the GTS PMA/FEC Direct PHY Intel FPGA IP.
