Interfacing HSMC Quad Video Daughter Card with SoCKit

Hello! I have this board (SoCkit) HERE : http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&no=816 , which I'd like to interface with the HSMC Quad Video Daughter Card HERE : http://bitec-dsp.com/product/hsmc-quad-video-daughter-card/ . My problem is that I do not understand the pinout of the HSMC connector used on the FPGA. The FPGA board user guide refers to the HSMC pins as AA28 and AA29 and so on whereas the schematic of the HSMC card refers to its pins as 1,2,3..100.. .The schematic can be downloaded from the bitec-dsp link above : http://bitec-dsp.com/wp-content/uploads/2014/05/hsmc_quad_video_schematics_rev2.pdf . For example it says that pins 119 and 120 are the I2C pins.Which pins do these 119 and 120 correspond to on the HSMC connector? 

 

 

I tried to attach screenshots, but couldn't.I apologize for any lack of clarity, but would be extremely thankful for any help!

Thank you for the prompt reply; However, I haven't been able to quite figure it out.I scrolled over to page 24 and it lists the HSMC connector and its configuration.The pins are referred to as AA_28 or AA_29, whereas no such reference is made on the schematic given with the Quad Card.I understand that this is a rather basic problem, but I'm stumped nevertheless.Perhaps you could be a bit more specific?

The AA_xx refer to the io pins on the fpga, the ones you use in the pin planner, these are connected on the pcb to hsmc pins in the table. You can use these to find the pinout.

Yes, I realize that these are the names to be used in the .QSF or the PIN PLANNER IO ASSIGNMENTS, but what I mean is that how do I know which "numbers" these pins correspond to? For example, AA_29 corresponds to the 119 or 120 or 121 or 163 or any other pin in the schematic attached? Please view the attached image.

NOTE : THE SCREENSHOT IS JUST A CUT OUT.It doesn't represent all the connections.
