I have configured NIOS using SOPC builder, however I am confused about how can I add the dual port memory so that its one end communicates with NIOS and the other end communicates with the control unit designed in verilog. Can somebody help me with this. Thanks

Hi,

In SOPC builder, you can add a new component. If you have written your function in verilog, you can connect one side to the avalon bus, as a slave and the other side export to the "outside world". This can be done by defining your signals in the component editor of SOPC builder.

Your SOPC system can then be used in a higher level schematic or HDL. Your exported signals are available for use.

I've attached an example of a fifo.

Good luck, Ton
