Built-in components
The library starts with ideal passives, sources, common semiconductors, amplifiers, switches, rails, and ground.
Resistor
Linear resistor. Value in ohms, e.g. 1k, 4.7M.
Capacitor
Linear capacitor. Value in farads, e.g. 100n, 1u.
Inductor
Linear inductor. Value in henries, e.g. 10u, 1m.
Transformer
Multi-winding transformer with explicit signed turns for winding ratio and polarity.
Diode
General-purpose rectifier or signal diode.
Zener Diode
Reverse-breakdown voltage-reference and clamp diode.
Schottky Diode
Schottky rectifier: low forward drop and no reverse recovery.
NMOS
N-channel enhancement MOSFET.
PMOS
P-channel enhancement MOSFET.
NPN
NPN bipolar junction transistor.
PNP
PNP bipolar junction transistor.
Controlled Switch
Four-terminal voltage-controlled switch.
Voltage Source
Independent voltage source. Pick DC/Sine/Square in the inspector.
Current Source
Independent current source. Pick DC/Sine/Square in the inspector.
AC Sweep
Voltage source preset to the AC kind — small-signal stimulus for AC sweeps.
Ground
Ground reference — its net becomes SPICE node 0.
Ideal Op Amp
Three-pin unpowered ideal operational amplifier.
Powered Op Amp
Five-pin supply-aware operational amplifier.
Comparator
Five-pin supply-aware voltage comparator.
Fully Diff Amp
Fully differential amplifier — complementary outputs centered on VOCM; Ideal or Single-pole.
Port
Subcircuit I/O port — its net becomes a pin of the enclosing .subckt.
