### unmap (component_referenceA:port_referenceA , component_referenceB:port_referenceB);

- The unmap keyword introduces the termination of the port mapping. The indices A and B refer to the two sides of the mapping.

- component_reference is one of the following:

  - a reference returned by the create operation,
  - the keyword self when referring to the component where unmap is given,
  - the keyword system when referring to the test system interface,
  - the keyword mtc when referring to the main test component.

- port_reference points out the port that should be released from the mapping.

Example:

unmap(vc_KompRef:Port11_PCO, system:Port2_PCO);

Port11_PCO of the component with the reference vc_KompRef is disconnected from the port Port2_PCO of the test system interface.
