LVDS and DE0-Nano

Hi,

I need to use LVDS on the NE0-Nano development kit, and I have a questions with respect to how to go about it.

From what I understand, I have two options:

  1. LVDS megafunction

  2. Parallel out into a LVDS transmitter chip

The problem I am having, is that I would like to use the megafunction but without any input. I would like to configure it so it generates dummy data. This way I can perform some simulations and measurements at the early stage of my project. Once that is working I can add the input and play with some real data. Also, is there another way of using LVDS but not the megafunction?

Any suggestions?

    I agree, this was more of a hack to be fair. I'm in the process of developing an expansion board for the Nano which will feature hardware LVDS serialisers and sensible connector for the output so I don't have to hack the original panel cable to pieces.

    I also have another dev kit (SoCKit) which features one of those HSMC connectors, I will take a look and check whether any of those differential output pairs are on 2.5V supply.
