How to read/write with quartus and NIOS

Hi all,

I'm using cyclone3 starter kit and quartus10.1sp1.

First I want to write value in NIOS at memory and read it in quartus.

After calculate in quartus(verilog), write value at memory and read it at NIOS.

I'm capable to write/read in NIOS(add a custom IP in SOPC, input value at memory address and see the value).

But I don't know how to do it in quartus(verilog).

Please inform me about it.

Regards,
