ETAS provides innovative solutions that drive the development of embedded systems for the automotive industry and related sectors.

With over 1,500 associates working in 12 countries in Europe, Asia, and the Americas, their customers represent a cross-section of the global automotive industry and related sectors. They include automakers, automotive component suppliers, ECU suppliers, and engineering service providers.


The automotive industry is undergoing fundamental change. New, energy-efficient vehicle powertrains, partially autonomous driving, digitalization, connectivity, and cybersecurity, the list of innovations has never been so long. At the same time, new systems must be brought to market faster. Key technologies are electronics and software, which is exactly where the strengths of ETAS lie. With their expert knowledge and the right tools, they enable the development of security-relevant software.

The increasing connectivity of vehicle electronics requires protection against unauthorized access, therefore, ETAS subsidiary ESCRYPT offers holistic solutions for embedded security, operational technology security, and enterprise IT security.

The range of products that ETAS offers is complemented by professional engineering and consulting services, premium-class customer service, and training programs. They also look to build strong partnerships with companies from the automotive industry to create added value for our customers, support additional use cases based on open interfaces, and enter new markets for further growth.

"Arm is an important partner for ETAS in the area of embedded software. Providing AUTOSAR products to support ECU development featuring ARM-based microcontrollers represents a significant part of our business."

Classic and adaptive AUTOSAR solutions

ETAS provides classic and adaptive AUTOSAR solutions to the worldwide automotive market.

RTA-CAR, their classic AUTOSAR stack comprises RTA-OS, RTA-RTE, and RTA-BSW (OS, RTE, and BSW components), in addition to RTA-FBL (a flash bootloader package) and RTA-SUM (Standard Utility Module). Configuration of the stack is provided through their ISOLAR-A and ISOLAR-B tools.

RTA-CAR provides support for a wide range of Arm licensee products, including single and multicore devices based on Cortex-M, -R, and -A devices.

RTA-VRTE, their adaptive AUTOSAR platform provides a comprehensive middleware solution for domain controllers and vehicle computers that supports execution and communication management, platform state and health management, persistency, update management, and more. Configuration and generation support is provided by their ISOLAR-A_ADAPTIVE tool – a member of the same tool family as ISOLAR-A and ISOLAR-B tools supporting a common approach to configuring systems of both classic and adaptive ECUs.

RTA-VRTE supports both QNX and Linux operating systems on a wide range of Arm licensee products using the ARMv8-64 architecture.

CycurHSM and CycurLIB from ESCRYPT, an ETAS subsidiary, are embedded security stacks and operate on a wide range of Arm licensee products.

Automated code generation with model-based design

New advanced Arm-based devices targeting high safety integrity functions enable disruptive market change. For increased adoption, engineering teams need a cost-effective way that ensure their Model-Based Design (MBD) workflows and code can be easily migrated to the new architecture, and that maximum performance can be achieved.

Operating as a subsidiary of Robert Bosch GmbH since 1994, ETAS is recognized as experts in automotive control applications and model-based design. Code generated with ASCET-DEVELOPER has shipped in over 450 million ECUs globally. Arm and ETAS collaborated to come up with a simplified workflow with ASCET-DEVELOPER and Arm Development Studio to make migration of existing projects to Arm architecture easier and achieve optimum runtime performance. The documented best practices guidelines delivered dramatic performance improvement on real-world powertrain algorithm (20%+) while only minor adjustments were required to controller model and generated code.
