6.5. Signal Polarity and FPGA Pin Assignment

Verify that the transceiver channel pin assignments—SYNC_N and SYSREF (for Subclass 1 only)—device clock, and SPI interface are correct. Also verify the signal polarity of the differential pairs like SYNC_N and transceiver channels are correct.

Check these items:

  • Review the schematic and board layout file to determine the polarity of the physical pin connection.
  • Use assignment editor and pin planner to check the pin assignment and I/O standard for each pin.
  • Use RTL viewer in the Intel® Quartus® Prime software to verify that the top level port are connected to the lower level module that you instantiate.
