<voltageprobe />

Overview

<voltageprobe /> records voltage values during SPICE simulation. It attaches to an existing node in your schematic and appears in the simulation graph output. Use probes to capture input/output signals or differential measurements across components.

Properties

Property	Description	Example
name	Optional label for the probe trace in graphs.	"VP_OUT"
connectsTo	Port selector that identifies the measurement node.	".R1 > .pin1"
referenceTo	Optional port selector for differential measurements.	".R1 > .pin2"

Add probes for every signal you want plotted in the simulation graph. When you provide referenceTo, the probe measures the voltage difference between the connectsTo node and the reference node.
