Mentor Graphics, Mecel offer Autosar 4.x software design solution

January 30, 2012 // By Christoph Hammerschmidt
With Autosar 4.x being in the design pipeline for a production start in 2014 to 2016, the automotive value chain increasingly demands development platforms. In order to meet this demand, Electronic Design Automation software vendor Mentor Graphics and Delphi subsidiary Mecel AB have joined their forces — and have introduced what they claim to be the first complete design environment for Autosar 4.x based software. The functionality includes configuration, code generation and implementation of BSW solutions for the Autosar versions 4.02 and 4.03.

With Autosar 2.x and 3.x being a success in the industry, version 4.x is expected to find even more acceptance — for the first time in its history, Autosar will cease to be a fast-moving target. According to the Autosar group's schedule, the 4.x versions will provide stable platforms for a long time. In 20014, Toyota will be the first OEM to start production of a car based on version 4.x of the Autosar standard software architecture, followed by Ford, GM and BMW in 2015. But the OEMs are already in the process of developing ECUs running under Autosar 4.x. General Motors by far leads the pack with 85 different Autosar ECUs currently under development, followed by Volvo with 40. In BMWs labs, 30 Autosar ECUs are currently being developed, Ford follows with 25 and VW/Audi with 20.

This huge design effort raises the demand for up-to-date design tools. The Mentor / Mecel tandem plans to serve this market for the years to come with its comprehensive tool package. Besides offering full flow coverage from design to implementation and test, the software is integrated and modular, promises Joachim Langenwalter, Director Automotive Network Design for Mentor Graphics. The tool collaborates with all different other tools supporting Autosar — for instance Matlab Simulink, the ubiquitous automotive software design tool. It also is standards based in that it is compliant with Eclipse, Artop, Sphinx and Genivi. It also meets the requirements for functional safety levels ASIL A to D, described in ISO 26262.

Mecel contributed its existing Picea family of BSW, RTE and configuration tools to the environment. Within the scope of their collaboration, the partners jointly implemented different building blocks of the configuration tool and the Autosar software stack and promise that these parts seamlessly interact.

The tool will be sold by both partners to their respective customers, albeit under different names and in different packages. Mentor's Autosar BSW solution contains the
