master other than NIOS cpu

hi all,

I am using Quartus SOPC builder to make a system. But I am using my microcontroller(8051) as cpu. For that if i connect a single slave, it is working fine but if connect more than one, none of them work. What may be the problem?

Thank you.

    1 - Are you obeying the waitrequest rule?

    2 - Is your address map correct?

    What is the failure mode? In what way is it "not working"?
