You must explicitly tell LTspice where to find the text-based subcircuit definitions. Click the button ( .op icon on the toolbar).

Extremely fast simulation times; low convergence errors. Cons: Does not accurately simulate "On-Resistance" ( RONcap R sub cap O cap N end-sub

The small current flowing when the switch is off. cd4051 spice model link

The most technical discussion and direct access to a functioning CD4051 subcircuit model can be found on the LTspice Groups.io forum.

Analog switches can introduce sharp discontinuities into simulation matrices when switching states instantly. To resolve convergence issues: Add a small capacitance (e.g., ) from the analog output pin to ground. You must explicitly tell LTspice where to find

Understanding and Simulating the CD4051 Multiplexer: Spice Model Guide

If you do not have a dedicated 16-pin multiplexer symbol, you can use the generic mux8 symbol provided by LTspice or create a custom one. Open the symbol editor. Cons: Does not accurately simulate "On-Resistance" ( RONcap

The most accurate behavioral and structural models come directly from the primary manufacturer.

SPICE (Simulation Program with Integrated Circuit Emphasis) is a powerful software tool used to simulate and analyze electronic circuits. The accuracy of SPICE simulations heavily relies on the quality of the component models used. An inaccurate or incomplete model can lead to misleading results, which can be costly and time-consuming to debug.
