Testbox with a Lattice FPGA

Hey folks,

I got a project to do, it should be a Testbox for a DUT.

The DUT includes a FPGA which reads a dedicated protocol defined by customer. The signals are LVDS.

I am not familiar with FPGA's, would it be possible to connect the FPGA with a different FPGA via LVDS an emulate the protocol?

What would you recommended to do and what should I care for?

Cheers!
