Do not rename the files. The index file must match the library name.
To simulate the WS2812 correctly, you will likely need to load a into your microcontroller (like an Arduino) that uses the Adafruit_NeoPixel or FastLED library. Since Proteus simulation is CPU-intensive, keep the number of LEDs in your simulation small (e.g., 8–16) to avoid lag.
: Searching for "Proteus WS2812 simulation model" on GitHub reveals open-source user contributions that simulate varying lengths of NeoPixel strips and rings.
