Pin Labelling

FPGA user signals connected to B2B connectors are characterized by the "Vx_IO_yy_p" naming convention, where:

  • Vx defines the FPGA bank (x = bank number);
  • IO defines an "FPGA to B2B" signal type;
  • yy defines a differential pair or signal number (yy = pair number);
  • p defines a differential signal polarity (P = positive, N = negative); single ended signals do not have this field.

Remaining signals use custom names.
