3.1.7 Time and Frequency

The keywords Time and Frequency can be used in the value fields of netlist entries to refer to time and the complex Laplace frequency, respectively. For example, the netlist entry

{L1, {2, 3}, L[Time]}

defines a time-variant inductance, and

{VC2, {1, 2, 3, 4}, Frequency*C}

defines a transcapacitance, i.e. a voltage-controlled current source with a transconductance that depends linearly on frequency.

Upon setting up circuit equations, the keywords Time and Frequency are replaced by the symbols that designate time and frequency as set in Options[CircuitEquations] (see also Section 3.5.1). The following analysis mode specific settings are performed:
