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.
