hei,

i am using an nios2, cyclone 2 developmentboard. i also used the reference design \niosii_cycloneii_2c35\full_featured. i added hardware divide to that design in sopc. when i try to use hardware divide in nios2 ide when i am debugging on the developmentboard the divu instuktion doesn't work. is that because the system is running to fast for the hardware divide? (85mhz).

is there any possibility to turn on software divide in nios2 ide, so i don't ned to resynthese the hole system. ?

Whether or not one design has speed issue can be confirmed by reading Timing Analyzer Tool.

Turning on software divide in CPU configuration, basically any change ever done to SOPC system, recompilation is necessary.
