Pin Assignment Simulation models may have their pins numbered differently than the corresponding supports the .plot directive, it cannot be used in current versions of KiCad. Differential voltage Probing differential voltages usually requires a simulation symbol. One is available in Simulation_SPICE:VOLTMETER_DIFF in the official libraries. This symbol has two terminals for differential voltage sensing, and one the user can probe. NOTE A SPICE model called kicad_builtin_vdiff
