problem in building new SOPC component

Hi,

I have a probelm in building a new SOPC component. I have this new

component, the PWM example, and a NIOSII cpu in the project. The

PWM works fine (using signalTap, I can see all the read/write control

signal changes). However, my new components does not work (with

signalTap, read/write control signal does not change. only address

change, but not the way I need).

Any idea what's going on will be appreciated?

Whether I need start a new slave_avalon bus? I think I using the right

address for my new module.

Thanks a lot,
