Simulate board bring-up before the prototype
Prev. Bloomberg · Gyfted. Systems and simulation infrastructure — the engine that runs your firmware against the circuit.
Bring-up is where schedules slip: quiet buses, brownouts, “works if I reset twice.” Simulation will not replace a scope on a real rail — it clears the silly failures before you join the lab queue.
Shift-left the bring-up checklist
Power sequencing relative to firmware, default pin states, I²C/SPI enumeration, interrupt wiring — exercisable as soon as netlist and image exist.
Keep a regression suite
Once a bring-up path works in simulation, gate firmware and schematic changes on it. Prototype #2 should be about physics, not rediscovering pinmux.
Hand-off to the bench
Same binaries, same tests where possible. Instruments take over for rails and sensors; the twin already proved the digital contracts.

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.
