When using the DFX Decoupler in IP integrator and when the interface is created and the VLNV is subsequently changed, the VLNV property of the port pins do not change. Consequently, the IP integrator does not allow connections to the newly changed ports, because it still appear as the old VLNV type. As a work around, execute the following procedure:

  1. Change the VLNV
  2. Save and Close the BD
  3. Reopen the BD to verify the changed VLNV
