Re: [Gems-users] Virtual Networks in MOESI_CMP_Directory

[Enric Herrero <enricherrero@xxxxxxxx>]

We have seen that in the MOESI_CMP_Directory protocol
foo and goo message buffers are defined and also their
corresponding IN_ports and OUT_ports. But these ports
don't produce any event or change of state in the
protocol and they are never used by any action.

In the L1 memory:

  in_port(goo_in, RequestMsg, goo) {
    if (goo_in.isReady()) {
      peek(goo_in, RequestMsg) {
        assert(false);
      }
    }
  }

In the directory:

  in_port(foo1_in, ResponseMsg, foo1) {
  
  }

Does that mean that we can remove them?

Thank you

Marco and Enric
