ABM sources

ABM sources generate an output waveform based on a user-defined expression. Voltage and current output ABM sources are available.

ABM (analog behavioral modeling) sources are much more powerful than linear or polynomial controlled sources because the controlling expression for ABMs is more arbitrary and easier to use. The expression is specified as a mathematical equation which is supported by a large set of mathematical and logical functions and operators. 

Any number of node voltage and branch current variables may be used within the controlling expression. For this reason, the ABM sources do not rely on pins for their inputs. The simulation time may also be used as a variable.
