Run thousands
Cost is compute, not calendar.
00 / Software in the loop
The code is real.
Everything else is modelled.
Run your production ECU software against a simulated vehicle. From week one, on any laptop.

01 / The window
Testing starts before the hardware does.
Control software exists long before there is a board to run it on. A virtual loop is the one available in that window, and it does not close when the hardware arrives.
Requirements
Plant model
Software build
Prototype hardware
Production
Programme phases are the general shape of a development programme, not a Validative process. Where the handover falls on yours is a question for an engineer.
02 / What is real
The same binary, the same control logic, the same calibrations.
The production binary stays real. The vehicle around it is modelled.

Production sourceThe code that ships.
Control logicEvery branch and fault path.

TimeRuns faster than the clock.
Models are approximations. This moves most testing earlier. It does not replace the bench.

No bench, no queue
Everyone runs at the same time.
03
The same tests, later
The same suite runs on real silicon.
04 / Capacity
One bench. One engineer.
One simulated target. Everyone.
Add capacity with simulation. Keep the bench for what only hardware can prove.

One runs. Five wait.
05 / Continuity
Nothing is rewritten.
Tests that need hardware are marked. A simulated run skips them instead of reporting a pass it did not earn.
