SIL & HIL Test Automation

One test suite from your desk to the bench — software-in-the-loop to hardware-in-the-loop, no rewrite.

What We Provide for SIL/HIL Testing

Alefbits brings software-in-the-loop and hardware-in-the-loop testing into one workbench — the same suite, the same reports, from pure simulation to a full hardware bench.

One Suite, SIL and HIL

The same Python test code runs against a simulation (SIL) or real hardware (HIL); bus and node aliases make moving from desk to bench a configuration change, not a rewrite.

FMU Co-Simulation & Virtual ECUs

Plant models and virtual ECUs (FMU) run as first-class nodes for closed-loop controller validation, with deterministic virtual time auto-engaged for reproducible CI.

Hybrid Bench, Gradual Bring-Up

Simulated and real frames coexist on one logical bus — bring up one ECU on hardware while the rest stays simulated, and the tests don't know the difference.

Headless & CI-Native

The SDK and CLI run whole campaigns headless, producing JUnit, HTML, and JSON reports with an auto-captured trace for every run.

Powered by UCAN Studio

Our SIL/HIL testing is built on UCAN Studio, spanning its simulation, testing, and analysis capabilities.

UCAN Studio

The automotive software engineering platform behind our SIL/HIL testing — network simulation, FMU co-simulation, a built-in Python test framework, and full-stack trace analysis in one workbench.
