SOPC builder connection issues

Hi All,

I am using SOPC builder to use NIOS II processor and 2 on chip dual port memories.

I have connected one port of each memory to instruction and data master of NIOS processor. Now I want to connect the other 2 ports of memory(Avalon MM slave interface) to some outside user defined interface.

But I am not able to generate the system from SOPC builder till all ports are connected. Is there any alternative way in which i can generate the system without connecting the ports?

Attached is the snapshot of SOPC builder project.

Thanks in advance.

    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.
