The ELEXIR software ecosystem is comprised of the following components

Products

Studio

ELEXIR Studio is our development environment and runs on your development machine. It’s a per-seat installation for each developer. It allows to configure each vehicle (analog and digital connections to the real world), develop application code, check code against specification, compile code, simulate and test the code. Finally, it allows to deploy the compiled and digitally signed application through our public or your private App Store.

Develop

ELEXIR Develop is a modern Integrated Development Environment (IDE) that is used to create new projects, write code for features encapsulated in Apps and to debug and run this code in the Simulate or on a real car.

Simulate

ELEXIR Simulate is a virtual machine for your vehicle’s hardare that runs your code in a physics simulation engine. This allows to test and debug new code much faster and in parallel with other developers - without occupying a physical test mule.

Cloud

The ELEXIR Cloud is the Internet backend that provides connectivity between the development environment (Studio) and a single car or an entire fleet.

Fleet

ELEXIR Fleet keeps each car connected to Studio during development and also after production and sales. It provides means to collect and analyse live sensor data, issue remote functions in the car and to deploy fleet software updates over-the-air (OTA).

App Store

Every software developed with Studio is always validated and curated using the ELEXIR App Store. The App Store keeps track of version history, checks the integrity of software and the compatibility with each vehicle. It uses cryptographic chains of trust to ensure that the compile-time verification against a specification is adhered to down to each ECU present in a vehicle.

Runtime

The ELEXIR Runtime is part of the software stack present in ELEXIR ECUs in a vehicle. It provides easy access to standardised interfaces like distributed sensors and actuators and is the library to program against when using ELEXIR Studio.

Middleware

The ELEXIR Middleware is part of the software stack present in ELEXIR ECUs in a vehicle. It ensure trustworthy and reliable communication between each entity. It provides authenticty of messages and signals, error-recovery and error-awareness in case of failures, ensure compatibility of communication protocols at run-time and generally abstracts from low-level communication.

RTOS

The ELEXIR Real-Time Operating Sytem (RTOS) is part of the software stack present in ELEXIR ECUs in a vehicle. It is the lowest level software running on the microcontrollers of ECUs in a vehicle and it ensures safety-critical execution of Middleware code, Runtime code and finally application code written in ELEXIR Studio.
