Structure
This element does not have attributes. The elements are shown below, in a 
sorted per type fashion.
In case a 
list is printed after an element, it indicates that you can have many, otherwise it should be a single element. With a 
optional it tells the element is not required.

Details
       Define a port to have an electrical signal, which is 
current driven.
      
Type pdaPortModeCurrent documentation:
    Define an electrical current driven port.
    
      Define a port + signal/mode name - typical TE or TM, but you can can use other signal names
      if those make more sense, for example for multi-mode or more full-vectorial ports.
      
Type pdaPortModeOptical documentation:
    Define an optical port/mode. This will have optical mode name in it.
    
       Define a port to have an electrical signal, which is 
voltage driven.
      
Type pdaPortModeVoltage documentation:
    Define an electrical voltage driven port.
