Adding a custom component

Hi Supal,

Thank you very much for the response. You have understood my requirement correctly. But the solution you have provided is not elaborate.

I have worked on FPGA logic design, but I am new to embedded design. I am pretty conversant with Quartus tool, but am new to SOPC. I want to know how I can do the mapping using SOPC builder. I want to know how I can create the enable signal using some software instruction. Do I need to use the Avalon bus. These are the things I need to know. I want to know the procedure.

Is there some tutorial on creating custom components using SOPC builder. The user guide is not of much help.

regards,
