The order of the elements within the circuit description is not important, although it is recommended that source elements be placed at the beginning of a circuit description. The element type code (R, C, IOA, etc.) must be in the first column of an element record.
The first field following the element type code is the user given name for the element being defined. Following the name field are two, three, or four node names followed by a value if required. The name for ground nodes must be either '0', 'GND', 'Gnd', or 'gnd'.
For all circuit elements the element name and node names are text. The value field is a real.
Each element record describes one circuit element.
