How to make a differential signal by ALTGX Mega Core

Hello everyone,

How can you get the differential signal's ports for transmitter/receiver on ALTGX mega core ?

I could not find the related parameters on the Mega Wizard Plug-in Manager.

Mega Wizard Plug-in Manager always makes the single-end signal's ports, rx_datain[0] and tx_dataout[0] per each channel.

I use Quartus II 32-bit Version 13.1.0 for Cyclone IV GX, EP4CGX75CF23C7.

Many thanks for your support.

    Instantiate it in your design and assign the correct IO-Standard in the Pinplaner. The negative pin will be created automatically.

    Hello supernode,

    Thank you for your suitable comment.

    I have tried it, and confirmed that the negative pin automatically appears in Pinplaner.

    Thank you so much.
