Valid SPICE models for the CD4051 are readily available from Texas Instruments. For highest fidelity, the manufacturer model is recommended over generic "Analog Switch" macros. Engineers should be prepared to perform manual symbol creation in simulation environments like LTspice or ngspice, as the component is not always included in the standard library manifests.
