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 Renode fits
CPU platforms and execution stay Renode-class. HardLabs supplies board attachments and peripheral models so the twin matches the schematic, not a hand-maintained fanfic .repl.

What HardLabs does — join the design-partner pilot
We build a digital twin from your netlist, schematic, and BOM, run your real firmware against it, and fail CI when pinmux, buses, or timing contracts break — weeks before bring-up on hardware.
- A digital twin of your hardware, built from your netlist, schematic, and BOM.
- A virtual lab: scopes, logic analyzers, and firmware debuggers in simulation.
- Auto-flagging of power-sequence errors, output contention, and race conditions.
