Hi Jake,

I think the idea I had correspond to the# 2, which consists in create a internal component that just export the avalon bus (what you did in the example you given) , and separately I have my peripheral and I can it to the system in quartus.

Else, I don't understand the# 1. If you create a component with the editor and add an Avalon MM slave interface, , that does not create any pin on the system symbol.

For the# 3, I tried it, but the SOPC Builder give me the following error when I add my component to the system :

"Error: TestComponent: Setting top_level_hdl_module is not allowed when instantiate_in_system_module = false"
