Automated Generation and Integration of AUTOSAR RTE Configurations

Automotive Open System Architecture (AUTOSAR) is a system-level standard that is used worldwide by automotive companies and their suppliers to develop the standardized software development framework for automobiles. A Runtime Environment (RTE) is essential for any AUTOSAR software architecture. The information to conFigure the Runtime Environment (RTE), for any embedded Electronic Control Unit (ECU) design, is given in an AUTOSAR Extensible Markup Language (ARXML) file. Currently, these ARXML files are interpreted by the developer to manually create each configuration. That is a huge bottleneck in the design flow of software because of the drawbacks such as the cost and time spent having to manually write code. Also, manual code entry is not scalable for larger projects. Every time manual code is created it needs to be tested and verified to ensure ISO 26262 compliance. Creating an ISO 26262 compliant, RTE code generator is essential in the process of automating integration of AUTOSAR methodology in the design of ECUs. This paper describes the design of a Computer-Aided Design (CAD) tool that automatically interprets the given AUTOSAR XML files and then generates the corresponding optimized C code (*.h and *.c files). The CAD tool is optimized for run time and memory usage and is ready to use for generating any portion of the RTE automatically, while being AUTOSAR compliant.
