Real-Time Physics Models
Your simulation model, running in real time, anywhere.
One validated model, from desktop to HIL to ECU.
Simthetic turns your physical plant model into a fast, validated reduced-order model. It then delivers that same model as an FMU, embedded C code, a HIL model or a digital twin, and checks every build against your original.

What You Can Build
One validated model powers every stage of the V-cycle, from design to production.
Design and tune controllers
Close the loop on a ROM that runs 5–100x faster than the plant model. Iterate in seconds, then confirm the final controller back in Simscape.
Watch an AI agent tune a PI controllerCharacterize the full operating envelope
Run voltage sweeps, load sweeps and Monte Carlo campaigns in the time a single detailed simulation takes.
Stress-test edge cases
Run load dumps, faults and fast transients at scale, and flag every scenario where the controller loses margin.
Ship with a validation report
Every ROM is compared back-to-back against your high-fidelity model, with error per signal and a documented valid operating envelope.
Deploy to embedded hardware
Production-ready C code for microcontrollers and ECUs, with every build verified against the reference model before it ships.
Proven: an LLC resonant converter model running in real time on a microcontroller.
Run it as a digital twin
Stream live data into a cloud- or edge-hosted ROM for monitoring, virtual sensing and predictive maintenance.
How It Works
From simulation model to deployable real-time physics in four steps
Connect Your Model
Provide your detailed physical plant model. Simthetic handles the rest.
Simthetic Builds Your ROM
Automatically trained and validated: 5–100x faster than your original, with <2% error.
Validate Against the Reference
A back-to-back accuracy report against your original model, with the valid operating range stated explicitly.
Deploy Anywhere
The same artifact, exported as FMU, C code, a HIL model or ECU firmware. Each build is verified to match the reference.

Applications
Versatile technology for diverse engineering challenges
Why Simthetic?
ROMs execute orders of magnitude faster than physics-based models, enabling real-time execution, HIL testing and large design sweeps.
Engineers provide a physical model and get a validated, deployable model as output. No machine learning knowledge needed.
From cloud servers to embedded microcontrollers. One model, any deployment target, with C code generation verified against the reference model.
The same verified model runs on the desktop, on the HIL rig and on the ECU. No re-modelling, and no drift between stages.
Coming Soon
The Simthetic Platform
An online interface where engineers can upload physical models and receive validated, deployable Reduced Order Models — no machine learning expertise required. Upload. Train. Deploy.
