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

I have tried to import my design file to SOPC builder, the snapshot is attached, I'd appreciate if you can have a look and tell me if there are any errors.

Secondly, how can I access this custom built design while programming. The imported design in this case is a memory, which has to be written to through a DMA. Can you please give me some example, (a macro may be) about how to write to this memory.

Thanks
