The controlled generators described by arbitrary functions allow to define the functional or behavioral models of an analog circuit using mathematical equations. The voltage or current waveform is described by:

V=expression or I=expression

The value of V or I determines the voltage across or current through the device. The expression given for V or I may be any function of voltages and currents.

# Inputs

Input | Description |
---|---|

V1 | First control voltage. |

V2 | Second control voltage. |

V3 | Third control voltage. |

I1 | First control current. |

I2 | Second control current. |

I3 | Third control current. |

# Parameters

Parameter | Description |
---|---|

Value | Expression defining the source waveform. This value is used only if the EXPR parameter is not specified. |

EXPR | Expression defining the source waveform. If omitted, it will use the expression specified in the value. |

# Example

Power expression: V1*I1

Voltage summer expression: V1+V2
