Get memory address out from Qsys system

Honored Contributor II



I have a Qsys system with two NiosII processors sharing one memory device, for both instruction and data.  

I need to get the data memory addresses produced by the two processors out of the Qsys system, while the system works normally.  

Is it possible to do this using a custom component connected to the Qsys avalon interconnect? (Processors see the custom component as the memory device. The custom component forwards the addresses to the actual memory, as well as to the vhdl toplevel outside)? 


I appreciate any suggestions on how to do this. I should say I'm new to FPGA based systems. 


Many thanks.. Cheers !
