  39 <p>The operation is used to map the ports of a test component to the ports of the test system interface.
  40 <ul>
  41   <li>The operation directly maps one port to another with the <b><font face="Courier New">in</font></b> side mapped to the <b><font face="Courier New">out</font></b> side and vice versa.;</li>
  42   <li>a port may be mapped to several ports (<b><font face="Courier New">map</font></b> used several times);</li>
  43   <li>the messages (signatures) defined for both ports must match, i.e., the incoming port must be able to receive all outgoing messages from the mapped port;&nbsp;</li>
  44   <li>one side of the connection must be the test system interface.</li>

  69   <p>The <b><font face="Courier New" color="#003258" size="4">map</font> </b>keyword introduces the port mapping. The indices A and B refer to the two sides of the mapping (one of them must be the

  73   <p><i>component_reference</i> is one of the following:</p>
  74   <ul>
  75     <li>a reference returned by the <a href="create.html"><b><font face="Courier New" color="#003258" size="4">create</font></b></a> operation,</li>
  76     <li>the keyword <a href="self.html"><b><font face="Courier New" color="#003258" size="4">self</font></b></a> when referring to the component where <b><font

  91 <p>The component of type Komp_CT is created in the first line.<br>
  92 In the second line, its reference (vc_KompRef) is used to point out the port on the side A of the mapping (vc_KompRef:Port11_PCO).<br>
  93 On the side B of the mapping is the port called Port3_PCO of the test system interface.</p>
