HDL Coder, Assigning specific pins to IO signals for a custom FPGA

I would like to know what the mechanism is for assigning specific pins to inputs and outputs when using HDL Coder. I have a custom FPGA design using an Altera Cyclone 2C35 672pin FBGA.

How do you assign specific pins? is it a control file, a parameter box that I havent found or something specific that I have to set up before I produce my model?

You need to Set Target > Set Target Interface

See the example where you can map the ports to interfaces as follows:

• For Blink_frequency and Blink_direction input ports, select the AXI4-Lite interface.
• For the LED output port, select External Port.
• For the Read_back output port, select the AXI4-Lite interface
