problem with niosII

when i try to run my program as NiosII instruction set simulator this warning appear,i dont understand how to solve it:

**** build of configuration debug for project farha ****

make -s all includes

compiling hello_world.c...

linking farha.elf...

info: (farha.elf) 39 kbytes program size (code + initialized data).

info: 2009 kbytes free for stack + heap.

post-processing to create ext_flash.flash

hardware simulation is not enabled for the target sopc builder system. skipping creation of hardware simulation model contents and simulation symbol files. (note: this does not affect the instruction set simulator.)

post-processing to create onchip_ram.hex

build completed in 12.781 seconds

what shall i do to have a result.

i'm working with niosII ide(v9),quartus(v9),cycloneII
