A PCB digital twin firmware can actually boot
Prev. Bloomberg · Gyfted. Systems and simulation infrastructure — the engine that runs your firmware against the circuit.
“Digital twin” is overloaded. For embedded teams it only earns the name if the twin executes the shipping image against the topology you drew — and admits what it cannot prove yet.
Built from design-of-record files
Netlist, BOM, optional schematic docs. Same package you already produce for fab. The twin is not a parallel CAD database; it is a derived, runnable view.
Honest coverage beats false confidence
Missing chip models and unsupported buses show up as gaps. A green platform load with silent omissions is worse than a failed generate — we refuse the silence.
Where the simulator fits
The processor runs your unmodified firmware image. HardLabs supplies the board around it — buses, wiring and peripheral models — generated from the schematic, not a hand-maintained board file.
HardLabs
Send us your design. We'll send you a simulator.
We build a board simulator from your netlist, schematic, and BOM, run your real firmware against it, and fail CI when pinmux, buses, or timing contracts break.
- A working simulator of your board, built from netlist, schematic, and BOM.
- Peripheral models attached so your firmware can talk to the board.
- A setup that runs your real firmware binary — no rewrite required.
