What it is

A minimalist digital logic simulator built in Unity (C#) that lets users design and test circuits by connecting logic gates, adders, and other chips visually. It's the reference implementation for Sebastian Lague's educational video series on how computers work, supporting both interactive play and programmatic chip definitions via a custom chip format. Standard Unity project structure: Assets/Scripts/ contains the core engine (DLS.asmdef), Assets/Build/ holds the production scene (DLS.unity), and Assets/Dev/ isolates video tools and experimental code (DLS.Dev.asmdef) to avoid polluting builds. Custom chip data likely lives outside the repo or in a save format handled by…

Start here

Open these first:

  • Assets/Scripts/Description/Types/ChipDescription.cs — Core data model for chip definitions; every logic component in the simulator is described by this structure.
  • Assets/Scripts/Description/Types/ProjectDescription.cs — Root project container holding all chips and circuit definitions; required to understand project persistence and composition.
  • Assets/Scripts/Description/Serialization/Serializer.cs — Handles JSON serialization/deserialization of all circuit and chip data; critical for load/save functionality.
  • Assets/Scripts/DLS.asmdef — Main assembly definition that organizes the core simulator codebase; defines dependencies and compilation boundaries.
  • Assets/Build/DLS.unity — Main scene for the built application; entry point for the runtime simulator.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Check README for instructions.

Daily commands:

Open the project in Unity 2019.3+. In the editor, press Play on Assets/Build/DLS.unity for a release-like build, or Assets/Dev/VidTools/Scenes/Dev.unity for full dev tooling. Export via File > Build Settings > Build.

Key cautions & unknowns

  • Slowing — last commit 12mo ago
  • Single-maintainer risk — top contributor 95% of recent commits
  • Unity version is not specified in the file list—check Assets/ProjectSettings/ProjectVersion.txt before cloning. The Dev and Build scenes use different assemblies (DLS.Dev vs DLS), so uncommenting Dev code in Build may…
  • Published-advisory coverage was unavailable for the captured dependencies.
  • Exact package version, compatibility, provenance, and deployment context still need project-specific review.
