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 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.
