VAL
Virtual OTA Validation — Validate software updates on simulated devices before deploying them to real hardware.
tQCS works with LG Electronics to deliver LG VAL to customers, supporting the evaluation, integration, and application of virtual OTA validation within the customer’s development environment. LG develops the validation platform; tQCS supports the customer-facing work — assessing fit, integrating the solution with the customer’s systems and OTA environment, and providing ongoing technical support.
Virtual OTA validation with simulated targets and scenario-based testing
Test software updates against simulated devices before they ever reach real hardware.
Why Test OTA Virtually?
Most OTA failures happen in situations that are hard to reproduce on a bench: a network drop halfway through a download, a server that answers late, or an ECU that returns the wrong code. Setting these up on real hardware takes time, and many of them are difficult to trigger on purpose.
LG VAL is built on LCOS (LG Common OTA Validation Platform), the tool LG uses to validate its own OTA updates. It runs test scenarios against simulated targets instead of physical devices, so teams can check how an update behaves when things go wrong, repeat the test as often as needed, and do it before any hardware is on the desk.
Key Capabilities
OTA testing against simulated targets
Scenario-based validation
Reusable LCOS core architecture
Product-specific protocol plug-ins
Separate protocol simulation server
YAML and JSON test scenarios
AI-assisted scenario generation
AI-assisted execution-log analysis
Logging and reporting
Support demonstrated in RTOS-based IoT and automotive environments
Scenario-Based Validation
Test scenarios are written in YAML or JSON.
They can be created directly by an engineer or produced through an AI module connected to LCOS.
The AI module can also analyze execution logs and report what failed and why, supporting analysis after a test has been executed.
Reusable Validation Architecture
The LCOS architecture is designed so that the common validation core is reused while product-specific protocols are handled through plug-ins.
This enables the same core architecture to support different target environments without rebuilding the validation platform for every product family.
LCOS has been utilized with RTOS-based IoT devices and automotive environments.
