LTspice (free, best for beginners), ngspice (open-source), PSpice (commercial), HSPICE (high-precision). 2. The Core Components of a SPICE Netlist A netlist is the text description of your circuit. Every line follows this pattern:

1. What is SPICE? SPICE is the industry standard for analog circuit simulation. It solves Kirchhoff’s laws numerically to predict DC, AC, and transient behavior before you build a physical prototype. spice circuit
