Honored ContributorSimulation NIOS II and VHDL block
Hi everybody,
I have a problem to simulate 2 block on quartus together. In fact there is one NIOS II block and one VHDL block that i want to use in dual mode. So first during the simulation, is the NIOS block that command the system and then when i give a command,i want to switch to the VDHL block. So to do this i have created another VHDL bock that take as input all the output of the NIOS II block and the VHDL block, and implement a multiplex in output . There is no output when i do so, but when i test the two block separately, there is successfull result. Best regards4 Replies
Altera_ForumYour post doesnt make sense. On the real hardware they would not run sequentially, they would run in parrallel all the time.
Why not post the code you're having problem with?- Altera_Forum
Hi Tricky
i have attached you all my code and a picture of the different quartus block.So let see and tell me best regards - Altera_Forum
Where are you seeing no output? Have you simulated the design? Have you simulated your wave_gen and dac_out together?

The output of the NIOS is visualized on the NIOS console and on the oscilloscope. the output of wave_gen is visualized in Quartus
