I have finally received all the hardware, and I want to start developing and testing my design. As a starting point, I am trying to figure out, how the signals incoming from my ADC are being transfered to the board (i.e. what every pin on the connector stands for). Are there any interesting references about the interfacing and specially about the HSMC connector on the boards?
I am working now with a TR4 FPGA Develpment board (from Terasic).

The TR4 support documents should have everything you need for the FPGA pinout. Typically what I do is find the schematic and the golden_top (top-level reference design) and create a Tcl pin assignments constraints file. I then look at the schematic to check the pin assignments. If the TR4 board ships with the OrCAD capture schematic, then its also possible to use Tcl from within capture to print out the net names connected to the pins on the FPGA (a nice way to get the pin assignments from the schematic).
As for the ADC board. What hardware do you have? The HSMC specification has the pin assignments for the LVDS and high-speed signals. The documentation for your ADC board should have details on what signals they have used on the HSMC connector.
