NettetThere are several steps to create your own model in LTspice. A model consists of a subcircuit and a symbol. For an example, we are going to build a model for a potentiometer. It will be based off the SparkFun 10k trimpot. A few months ago I designed a soldering kit for personal use based off the 555 timer. Nettet10. jul. 2024 · Normally, only current and voltage are specified as initial conditions in a circuit using a SPICE-based simulator. The current and voltage may exhibit a decaying oscillation if the damping constant in the circuit is low.
