how to use niosII ide

Hi,

i have a program written in vhdl.I want to implement this program(after transforming it into bloc .bdf conneccted to the nios standard).

I want to know if i would rewrite this program with the nios compilator(nios II ide)or i would juste declare inputs, outputs,signals used in my program and the fonctionnement will be automaticallay done as it's written in vhdl.

I dont understand what do i do exactly:confused::confused::confused:

    The Nios IDE is a tool to write "software" that can run on the NIOS (a soft-core processor inside an Altera FPGA).

    The code you have in VHDL is synthesizable into Altera FPGA gates, and produces "hardware" structures.

    There is no way to automatically translate "hardware structures" (VHDL) into "software" that runs on a processor inside an FPGA.

    And even if such a tool would be available it would be highly unefficient.

    What is very efficient is to combine a NIOS with VHDL. Then you get efficient code (VHDL) with the flexibility of software on top; the best of both worlds.

    So please read some more documentation so that you can find out what you really want and need.
