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 isn't limited to basic gates. It supports several levels of design: Basic gates (AND, OR, NOT, XOR, NAND). Medium-Level: Latches, Flip-flops, Muxes, and Decoders. cedar logic simulator

Ideal for introductory Digital Systems Design (DSD) courses. Hobbyists have shared screenshots of Cedar Logic circuits

: Includes everything from basic gates (AND, OR, NOT) to high-level components like Multiplexers, Decoders, Adders, Flip-Flops, Registers, RAM, and ROM. It supports several levels of design: Basic gates

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
