There is no plan to retire Nios II feature at this point and in the foreseeable future.
I hope that helps.
If you have further questions, please do create a new thread. I will assign an engineer to support you.
I would like know for next 10 years Intel will continue to support Niosii? I'm asking because it's work related questions . we would like to use Niosii processor to design FPGA and keep it for next 10 years. we are afraid Niosii becomes obsolete. if intel support Niosii for next 10 years, it will be very helpful know .
