What kind of configuration are you trying to model? What you have here works in terms of putting multiple L2s between tol2bus and membus, but I'm not sure what will actually happen when you run the resulting simulation... if all of the L2s try to respond to a request, you'll get an error; on the other hand, if only one L2 responds to each request (maybe the first one that the request gets sent to) then your simulation may look like it's working fine but N-1 of your caches won't be doing anything.
