cyclone 3 differential input and output definitions

Hi FvM,

thanks for your reply.

So if I understand correctly I need to design a one port signal and define it as a differential one?

Additionally, When I defined the 11 differential outputs, I did so by using the mini lvds protocol, and there Quartus let me assign the differential pairs manually. Do you have any idea about the reason for it?

On a similar note, Could you point me to some good tutorials? I went through the Altera online training, and the google search gave lots of results, some seem ok but most don't.

Thanks,

Yarok
