Agents that watch the line

FIXT writes the test plan, runs the station, and catches drift before it becomes a failure.

01The problem

Test lines still need someone watching them.

Someone writes the scripts. Someone keeps the line running through every revision. When a unit fails, someone reads the logs by hand: board, fixture, or test?

Root-causing one failure pulls in failure analysis, reliability, ATE, and quality. Four teams, four slices of the picture, one meeting to compare notes.

That doesn't scale. Not with volume, not with how fast hardware changes.

02What we build

Full test coverage in days, not weeks.

01

Ingest

The schematic, the datasheets, the firmware. All of it.

02

Generate

A full test plan, with limits pulled straight from the parts.

03

Run

Runs the line. Stays watching through every revision.

04

Triage

Every failure triaged with the eye of four engineers, not one.

03Vision

The model doesn't test your board. The harness does.

In software, the harness is the loop around the model. In hardware, it's the rig around the board. We build the one that is both.

FIXT-Benchtriage accuracy

Same model, same boards. With the harness, and without.

Failures classified board / fixture / test against engineer ground truth, across bring-up runs on production boards.

Swap the model whenever a better one lands. The harness is the part that holds.

04Positioning

An operator, not a copilot.

Most AI for hardware is a copilot. FIXT runs the station, watches the line, and knows when something is wrong.

Runs the station

Executes the plan, cycle after cycle.

Watches the line

Holds the baseline across every shift and revision.

Knows when it's wrong

Separates a drifting fixture from a genuinely bad board.

See it running on your line.

One station, one fixture. Schematic in, a monitored test line out.
