How itsmezerog/logic-gate-simulator works
Purpose and Scope
A small C++ hobby project intended to simulate digital logic gates and wires. Supported gate concepts are AND, OR, NOT, NAND, and NOR; the README does not establish a GUI, persistence layer, or networked service.
Application Entry Point
src/main.cpp is the only source file shown and therefore the likely location for program startup, simulation setup, and any current gate/wire evaluation loop. There is no evidence in the tree of separate domain modules, libraries, or plugin boundaries.
Simulation Core
The logical model is expected to represent gate inputs, outputs, and wire connections, with basic gates composing the primitive behavior and NAND/NOR representing derived behavior. As the repository exposes only src/main.cpp, these responsibilities are currently likely colocated:
• src/main.cpp
Primary Control and Data Flow
The expected flow is: construct or define logic gates → connect values through wires → evaluate gate truth functions → propagate output values to dependent inputs. The exact evaluation scheduling strategy (single-pass, iterative propagation, event-driven, or clocked) is not documented and should be verified in:
• src/main.cpp
Build and Dependency Boundary
CMake is the project build-system boundary. Presets likely define supported local build configurations, while vcpkg manifests declare externally acquired C++ dependencies:
• CMakeLists.txt
• CMakePresets.json
• vcpkg.json
• vcpkg-configuration.json
Runtime and Infrastructure
The material runtime is a native C++ executable built through CMake. No server runtime, database, browser client, cloud infrastructure, or external API integration is indicated by the supplied repository tree.
Current Architectural Shape
The architecture is intentionally compact and monolithic: one executable source unit plus build/dependency metadata. Future extraction candidates, if the simulator grows, are gate abstractions, wire/net propagation, circuit orchestration, and user-facing input/output; none are presently represented as separate paths.
