General Format: .IC |V(|node #|)| = |value| ...|| .IC fixes the node voltage of node |node #| to |value| volts over the entire bias point analysis. Thus .IC tells PSpice the node voltage at time t=0 in the transient analysis. .IC is sometimes used to help the circuit easily converge (assuming you know the final value) or to set initial capacitor voltages. After the bias point analysis is completed the nodes are no longer held at the specified values and are able to change over time. Example : .IC V(5) = 0 V(7) = 5 The voltages at nodes 5 and 7 are set, respectively, to 0V and 5V for the duration of the bias point analysis.
