Porting source code to a new FPGA

Hi all

I would like to ask about porting a source code from old FPGA to a new one. Is it just compile or targeted its into a new FPGA and will be all done? Or how does it goes? Really need an advice here. I'm new to FPGA

Thanks and Regards

    You will also probably have to redo some assignments, such as I/O standards and pins. What are the original and the new FPGAs?

    Thanks Daixiwen for your replied.

    The original FPGA is from flex 6000 (epf6016ti144-3) and the new one is from cyclone IV (EP4CE6E22I7N). There is a differences in between the I/O (OLD = 117 : NEW =91).

    I'm scared that it'll be a problems. What is your opinion sir?

    Thanks and Regards

    It shouldnt be a problem (apart from the pinout) - but any megawizard files MAY have to be regenerated, depending on how they were targetted.

    What may cause you problems is oldschool design habits if any exist - like latches, internal tri-states or LCELLS to delay signals.

    As for the I/O, how many does your design actually use? As long as it is 91 or less it won't be a problem.

    Check also the voltages. You will of course need to redesign the PCB, but you will also need different supply voltages for the FPGA, and if you were using 5V I/O with the Flex, you will need to adapt those I/O to the maximum 3.3V supported by the Cyclone IV.

    Attached is my compilation results from the source code with current FPGA.

    Is there any flow or tips for me to do for porting this code to a new FPGA?

    Thanks and Regards

    you could probably just take a copy of this project and change the device and pinouts for a start.

    thanks sir. Do you know is there any core that exist for MSK (GMSK) modulation and demodulation for implement in FPGA?
