Cyclone III pin assignment?????????

I am a beginner in this field of FPGA,

and I have to make a video converter (composite -> VGA) using CYCLONE III.

I finished the development of all blocks in verilog and I still have the implementation of my code in that famous FPGA.

my problem is the assignment of pins.

I can not find the table showing the pin assignments of such audio or video codec decoder (for example)....

can somebody help me please?

    Hi,

    the required pin assignments depends on your board. E.g. you have to look which FPGA pins are connected to VGA connector.

    Kind regards

    ... then you open the Assignments->Pins Quartus menu and you'll find a table/fpga-layout where you can constrain each internal signal to connect to the proper pin.

    In this case, u can use the user pins as output pins. See the list of user pins available and assign your outputs to those pins.
