The AcidBourbon blog gives complete instructions on how to use CD4000 series and 74HC series integrated circuits in your LTSpice simulation.
So, I was simulating a circuit in LTSpice and I wanted to use an 4000-series IC. Someone probably did that before, right? So I googled and found quite some posts mentioning the CD4000.lib or CD4000_v.lib library. But a lot of people are having quite some trouble using it. And soon I had the same issues and did not understand (it).
So let me quickly guide you through the steps that made this damn library work for me (without me necessarily understanding everything that is going on).
(The procedure is *exactly* the same for 74hc.lib, the only difference is to replace “VDD” with “VCC” everywhere.)

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
