Aditionally, you can't use LVDS with the DE1.

The GPIO pins are connected to a bank powered at 3.3V VCCIO.

For LVDS, they'd have to be connected to a back with 2.5V VCCIO and have the proper external resistors.

Among the examples and documentation of the DE1 board, you should have a mock up project that contains just an empty top level and all the correct pin assignments.

I suggest you take it as base for any project you do on the DE1.
