Cedar Logic Simulator -

❌

Hobbyists have shared screenshots of Cedar Logic circuits implementing a full 4-bit CPU with program counter, ALU, control unit, and RAM—all within the simulator. The timing diagram view allows debugging the fetch-execute cycle visually. cedar logic simulator

| Issue | Impact | |-------|--------| | | Accidental deletion means rebuilding a sub-circuit. | | Outdated Java dependency | Requires Java 8 or older; modern Java versions may need compatibility tweaks. | | No native 64-bit or GPU acceleration | Large circuits (hundreds of gates) slow down significantly. | | Limited export formats | No Verilog/VHDL, no SPICE netlist, no PDF printing. | | Minimal documentation | The help file is sparse; community tutorials are rare. | | No online collaboration | Browser-based simulators (CircuitVerse, Falstad) have surpassed it here. | ❌ Hobbyists have shared screenshots of Cedar Logic

: Allows users to monitor multiple signals over time, which is essential for debugging sequential logic. Pros | | Outdated Java dependency | Requires Java

Unlike some simulators that require you to "compile" and "run" a circuit to see results, Cedar Logic is "always on." As soon as you toggle a switch, the logic propagates through your gates, and the results are immediately visible on LEDs or hex displays. 2. Multi-Level Abstraction
