Why can't I enable the rx_patterndetect signal on the Custom PHY when in bit slip mode for Arria V GX and Stratix V GX devices?

Environment

  • Arria® V GT FPGA
  • Arria® V GX FPGA
  • Arria® V ST SoC FPGA
  • Arria® V SX SoC FPGA
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

You cannot enable the rx_patterndetect signal on the Custom PHY when in bit slip mode for Arria® V GX and Stratix® V GX devices because bit slip mode does not search for a specific pattern. You should slip the data manually until you achieve word alignment.
