The first result was a dead university FTP server from 2009. The second was a forum thread where someone asked the same question, and the only reply was: "Just use an ideal switch array, lol." She sighed. Ideal switches didn't capture the CD4051's notorious on-resistance variation or the crosstalk between channels. cd4051 spice model link

How to Use the CD4051 SPICE Model

For high-precision applications (e.g., audio switching), look for a transistor-level model (rare for CD4051). If you cannot find one, add external parasitic capacitors to your simulation to model crosstalk.
