Industrial grade FPGA firmware image can run on extended grade for cyclone 10GX

Our primary choice for the project is the Extended grade Cyclone 10 GX (10CX105YU484E5G), as it meets the required operating temperature range (0°C to 100°C) and is more cost-effective.

However, in case of supply shortages, we may need to use the Industrial grade version instead. To keep the firmware universal and minimize rework, I’d like to ensure that using the Industrial grade (10CX105YU484I5G) in our Quartus project won’t cause compatibility issues—specifically, that the same firmware image used for the Industrial grade can also be safely applied to the Extended grade.

We understand that using Extended grade firmware on an Industrial grade device might not hold due to differences in temperature specifications, timing, and power analysis. That’s why we're considering compiling our Quartus design targeting the Industrial grade device upfront. This way, we can ensure compatibility with both variants and switch between them depending on availability.

Before proceeding, I’d like to get official confirmation from Altera (Intel) to move forward confidently with this approach.

Thanks with regards,

Ayush

    Hello,


    The difference between -I (Industrial) and -E (Extended) grade is just temperature support of its package. Both can run the firmware. FPGA designers only need to take care of the timing closure of each design.

      Thanks for replying, So are you suggesting Industrial grade firmware can run on Extended grade without any issue ?

    Hi AyushIND,


    Just a reminder, please make sure to select the Industrial grade device in Quartus and recompile your design if you are using a design originally targeted for Extended grade (and vice versa).


    Once timing closure is achieved - no errors, the bitstream will be suitable for your Industrial grade device. Using a bitstream compiled for Extended grade is not recommended, as it may not be reliable.


    Let us know if you need any further assistance.


    Thank you.
