SOPC builder connection issues

you'll still need a component connected to the slave ports in SOPC Builder even if you're going to connect the masters outside of SOPC. you need to make a custom component that sends the relevant Avalon-MM master signals out of the SOPC system as conduits. i think if you create a custom component with the Avalon-MM master template, adjust to taste, then generate the custom component it will create a master that simply exposes the Avalon bus signals outside of the SOPC system.
