The invisible side of your PCB, revealed.

BangProof is PCB + firmware co-simulation for embedded engineers. Upload your board. Upload your firmware. Simulate the full electrical + digital behavior end-to-end — before you burn hardware.

What it does

See the physics that's actually running on your board:

Current flow — visualize how amps travel through every copper trace, reversing with your PWM, responding to your firmware's register writes.
Magnetic field — every current-carrying trace wears a field around it. The invisible cause of your crosstalk, your EMI, your ADC drift.
Thermal dissipation — the MOSFETs dumping switching losses. The inductor saturating. See exactly which watt went where.

Why it matters

Logic simulators skip the physics. Physics simulators skip the firmware. BangProof runs both.

Upload your PCB. Upload your firmware. Simulate the whole thing, together.

Who it's for

Embedded systems engineers, firmware developers, PCB designers, and hardware teams who want hardware-in-the-loop confidence without maintaining a HIL rig. Built on ngspice-class analog simulation paired with instruction-level MCU emulation.
