HalloWe have a DE0-NANO Board with EP4CE22F17C6 FPGA. Is it possible to download a file which is compiled for EP4CE22F17C8 and get it running on the DE0 NANO board, keeping the pin-out and all the other settings the same? As they are from the same EP4CE22 group and Altrea suggest that there is a vertical migration is possible. Can anyone please let me know if its possible and if possible how it can be done?
The only difference is the timing. A C6 is faster than a C8, so a project compiled for a C8 will work on a C6. The opposite isn't always true, but if you set the device to C8 in the settings then you will always generate a file that can be uploaded to both FPGAs.
To answer the question literally, you can always download the image because there's no distinction for speed grade. To be sure that it "works", you need to recompile it with C8 timing constraints.
