From KiCad netlist to firmware simulation

KiCad already exports connectivity. The missing piece for embedded teams is a path from that export to a runnable board under real firmware — without waiting on gerbers.

What to export

Netlist (.net / XML), BOM (CSV/Excel), firmware image. Schematic PDF helps when straps and addresses are not in the BOM. Keep the KiCad project as source of truth; HardLabs consumes exports.

What you get back

A platform description, coverage gaps for unmodeled parts, and a path into CI. Open-source ECAD does not mean unserious bring-up.

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.
