trouble generating system and compiling with SOPC builder

Is "test" the name of the generated sopc component or the name of the Quartus project?

In general you need to follow these steps:

- create a Quartus project, i.e. myproject

- define a top level entity, HDL or schematics: let's call it main

- use sopc builder to create and generate your component system; let's call it sopc_system

(at this point in Quartus project library you should have a new entity called sopc_system)

- instantiate sopc_system component into main

- build the quartus project
