2 months agoAssuming you are just bringing the old .qsys file into 25.1, have you tried manually regenerating the system first before compiling in Quartus? Did you get a warning/error about updating the Nios V IP for the newer version of the tool? If not (or if you did and you didn't update the IP), you should still try deleting the Nios V and then re-adding it to your system and then regenerating the system.
