TkGate: Open-Source Digital Logic Circuit & Schematic Editor
Discover TkGate, a free and open-source digital logic circuit and schematic editor for educational purposes and prototyping.
What is TkGate?
TkGate is an open-source digital logic circuit and schematic editor for Linux, Windows, and macOS. It provides an intuitive graphical user interface for designing and simulating combinational and sequential logic circuits.
Some key features of TkGate include:
- Intuitive diagram-based design for constructing circuits using common logic gates (AND, OR, XOR, etc.) as well as user-defined gates
- Support for hierarchical designs to manage complex multi-level circuits efficiently
- Simulation engine to test and debug circuit designs interactively
- Ability to export circuit designs as images or Verilog/VHDL code for integration with other EDA tools
- Multiplatform support running natively on Linux, Windows, and macOS
- Completely free and open-source released under GNU GPL license
While less feature-rich than commercial tools like Xilinx Vivado or Altera Quartus, TkGate provides an easy way for students, educators, and hobbyists to learn digital logic design principles without costly licensing or complex professional tools. Its simple interface and hierarchical capabilities allow moderately complex circuits with thousands of gates to be constructed and simulated with relative ease.
