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"?
