Circuit Simulator

This project provides a relatively fast and flexible Circuit Simulator. Note that this is NOT an emulator, but instead a gate-level simulation of the chip state. Accuracy is prioritized over performance, so it should not be used in situations where emulation is desired.

JSON Circuit Specification

The circuit can be imported into the simulator using a human-readable JSON file. This section defines the format for all of the components within the file.
