Honored ContributorNIOS II SOC SW Simulation Too Slow to be useful...
Has anyone seriously used simulation of a NIOS II SOC with SW to debug the design? Yes, I used AN351
to run and say "Hello World" in simulation but in a real full size SOC it takes forever to run. I tried a very simple program that write to LED_PIO, and yes it runs, but it mostly accesses SDRAM. What is needed is a NIOS II BFM that obeys the AVALON bus protocol but executes simple Read/Write (bus cycles) instructions from a stimulus file. It does not run any 'C' SW! Any suggestions?
