Altium connectivity into firmware simulation

Altium owns the design release. HardLabs consumes connectivity and parts identity so firmware validation is not blocked on assembly. Your libraries and release process stay put.

Bridge ECAD and embedded CI

When the schematic freezes, export connectivity and BOM, generate the twin, and keep firmware PRs honest against the board you intend to fab.

Sending an Altium design

Self-serve upload in the app reads KiCad and Cadence (OrCAD or Allegro) netlists today. For an Altium design, send the project's netlist export, schematic PDF and BOM with a pilot request and our team takes it from there.

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.

  • KiCad → simulation

    Take a KiCad netlist into firmware-in-the-loop simulation. Overlay the BOM, generate a simulated board, and test drivers before fab.

  • Firmware-in-the-loop

    Firmware-in-the-loop against your netlist — not stubs. Run unmodified .elf images on MCU simulation with board-aware I²C/SPI models and CI assertions.
