thank you for reply.

The fact is that the project i program didn't have a Nios CPU, i want to use SignaltapII to check my project.

As i set the unused pins as inputs & tri-state , so the CPLD didn't load the sof file from flash,(because the LED "loading"didn't turn on);but as i add signaltapII to my module ,when i program down to the board,CPLD load the sof file from flash,the LED "loading" blinking and then the LED "user" turn on.so the signaltapII just couldn't work.

The board i use is nios pro stratix 1s40,i think something in signaltapII was set wrong like pins.
