LLMs can generate simulation models fast, but the output is often inconsistent and hard to validate. SPX’s DSL makes model generation safer and faster by enforcing a constrained structure, clear naming rules, and a workflow with validation, runtime smoke checks, and CI gates—so teams can ship repeatable simulations with confidence.

Spin up a working KNX simulator in minutes with SPX. Launch a ready-made ABB JRA/S4.235.1 shutter actuator model, validate live group address updates, and observe realistic blind position/tilt changes. Ideal for smart-building integration testing, scenario-driven validation, and repeatable CI-ready workflows—without physical KNX hardware.

Spin up a working BACnet simulator in about 5 minutes with SPX. Run the setup wizard, open the SPX UI on localhost:3000, launch a ready-made BACnet instance, and verify discovery plus live object values using a BACnet client tool. Perfect for fast smart-building integration testing and CI-ready baselines—without physical devices.
