Migrating FPGA Code from Cyclone IV to Cyclone III

Hi All,

I would like to know if I can migrate a Cyclone 4 FPGA design to a Cyclone 3 FPGA? If yes, what are the steps involved in migration?

For Cyclone 4, I'm using EP4CE115F29 device.

For Cyclone 3, I'm planning to use EP3C120F780C7N device.

Regards,

Den

    Firstly you could migrate your design and after that your device :

    - regenerate all the megawizard component by targeting the cyclone 3 (NIOS, FIFO, PLL etc)

    - change the device to cyclone 3, specify the relevant configuration mode, special signals eventually used (crc_error, init_done), power dissipation modes etc...

    - compile the design with Quartus

    - allocate the IO banks and pins to be ok with your PCB board placement

    hi pantxoa,

    thanks for giving me an idea on where to start.

    i'm gonna try it out. will start importing/adding components that I need in my project in SOPC builder.

    i will definitely send more questions if I encounter problems.

    regards,
