Port mapping of Software Component
7/25/2013
 Challenges
 Difficult Navigation
 Undesired data flow in case of improper mapping
 Time consuming due to repetitive Validation and correction
Probable Solution
 Advanced GUI
 Filtered Options
 A drag and drop to connect ports
 Runtime Validation

12. © KPIT Technologies Limited
2. Data to Signal mapping
7/25/2013
Data Mapping Problem
• Absence of Data to Signal (AUTOSAR Data Packet) mapping in System Extract
• Many objects to be created - Traditional method is too time consuming
• Tedious to do for 1000+ signals
Probable Solution
 Import data files in the AUTOSAR Environment through DATA
editor
 A Data to Signal Mapping tool
 Reduce Manual creation
 Map associated elements internally

3. RTE runnable to OsTask Mapping
7/25/2013
 Actual ECU functionalities are mapped to RTE runnables
 For a complex ECU this number would be quite high
 Easy way out - One RTE runnable to one OsTask
 Not an optimal way – High CPU Load!
 Multiple runnables to one OsTask will be desirable
 RTE Editor to map many runnable to one OsTask
 Optimal and easy to debug
 Support for mapping of Data Received Events and Timing Events in an AUTOSAR
environment

4. BSW Stack Configuration
7/25/2013
 Manual Configuration
 Vendor Specific Parameters
 Difficulty in configuring correct values
 Demands exhaustive BSW Configuration knowhow
 Time consuming to configure the entire BSW Stack

15. © KPIT Technologies Limited
What could be the solution?
7/25/2013
• AUTOMATION!!!
 Intelligent Configurator Tool
 Reduce manual configuration
 More reliable
