Hardwave models hardware as a dataflow graph of components. Each component is a typed black box with input ports, output ports, and a solver that turns inputs into outputs. Connect components into a graph, run the simulation engine, and get results: from a simple voltage divider to a full robot drivetrain.

​
Why Hardwave?

Hardware prototyping is expensive and slow. You design something, order parts, assemble it, test it, and discover a motor draws twice the expected current. Then you iterate. Hardwave lets you close that loop in software:
  • Simulate electrical, mechanical, and thermal behaviour before buying anything
  • Compose components into systems. A resistor, a motor driver, and a microcontroller all share the same interface
  • Calibrate simulation models against real measurements from physical hardware
  • Swap solvers: start with a formula, replace it with a hosted ML model trained on real data, without changing any wiring

​
Quick Start

1

Install Hardwave

Install the Python package and import the standard library to register built-in types and components.
2

Build a graph

Add component instances to a SimulationGraph and wire their ports together.
3

Run the engine

Validate the graph, then call SimulationEngine.run() for steady-state or transient results.

Core Concepts

Everything is a component. A resistor is a component. An Arduino is a component. A robot arm is a component. The abstraction never breaks.

​
Component health and faults

Stdlib components like DCMotor and LiPoCell monitor operating limits during simulation. When a motor overheats or a battery over-discharges, the engine records structured diagnostics and can degrade component outputs, making it possible to stress-test power supplies, validate shutdown firmware, and teach failure modes before hardware breaks.

Component Faults and Health

Runtime warnings, fault codes, and FaultMode configuration
