Logisim Evolution
Logisim Evolution is a digital logic simulator and schematic editor used for designing and verifying digital circuits. It functions as a tool for digital circuit design and real-time logic simulation, allowing users to create schematic representations of electronic hardware using gates and registers.
The software distinguishes itself by providing hardware description language tools that allow for the definition of custom component behavior and the translation of visual schematics into synthesis-ready code for FPGA hardware deployment. It also serves as a bridge for physical hardware integration, mapping simulated designs to physical electronic boards for validation.
The platform covers a broad range of capabilities including timing and signal analysis via chronograms, hierarchical subcircuit encapsulation for reusable component grouping, and memory state management for RAM and ROM components. It further supports the export of circuit designs into vector graphics formats and the extension of hardware modules through pluggable component libraries.
The project is implemented as a cross-platform Java application.
