12 Model based development Bosch ECU Model based Commissioned Software sharing Model Sharing func Exchange of models and model artefacts in order to ease Software development and cooperation between two or several partners 12

13 Better cooperation with OEM : 5 levels of Model-Sharing Cooperation Levels Level 0 Level 1 Level 2 Level 3a Level 3b Level 4 Description Processing of Bosch model Build simulation environment at customer Non functional adaptation and processing of customer model No delivery of model artefacts to customer Non functional enhancement and processing of customer model Delivery of enhanced model and model artefacts to customer Functional modification of customer model Delivery of modified model to the customer Functional modification of Bosch model by customer Delivery of modified model to Bosch Joint development Comparable level of contribution from Bosch and customer Sharing of created Intellectual Property 13

14 Matlab / Simulink tool chain as open system Support of different role-based tasks at OEM side Enhanced use of Matlab strengths : scripts Processing of OEM Data Dictionary (database) Automated t processing of OEM models to Robert Bosch system for code generation Establish standards (MDX and/or AUTOSAR) used for code generation Ease definition of a common reference development process Ease specific OEM / supplier developments Increase the quality and reduce the low added value tasks Reduce the development time Provide a frame to reduce the customisation for each OEM Ease the integration in 3 rd Party Software 14

15 Front-loading process : back-to-back tests with MIL / SIL OEM Data Dictionary OEM model Matlab Workspace Implemented model (fixed- or floating-point) Code generation Compilation HEX Stimuli from OEM Additional test cases to improve the coverage Stimuli + test cases MIL tests with Test Execution Tool SIL or PIL or HIL tests with Test Execution Tool MIL results SIL or PIL or HIL results Back to Back Comparison 15
