The FPGA device footprint and pinout for the Cyclone IV family is very similar. This design should fit with small or no changes to other Cyclone IV devices.
This is a PCB design I did to test Altium Designer's capabilities. I haven't tested it so I thought I could share the design.
Hi ! fist of all i want to thank you for the project , then i want to know how does the cyclone IV recognize the other devices? thank you
