Challenges
Difficult Navigation
Undesired data flow in case of improper mapping
Time consuming due to repetitive Validation and
correction
Port mapping of Software Component

Probable Solution
Advanced GUI
Filtered Options
A drag and drop to connect ports
Runtime Validation

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
2. Data to Signal mapping
© KPIT Cummins Infosystems Ltd. 11
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
www.kpitcummins.com | autosar@kpitcummins.com
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
3. RTE runnable to OsTask Mapping

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

Manual Configuration

Vendor Specific Parameters
Difficulty in configuring correct values
Demands exhaustive BSW Configuration knowhow
Time consuming to configure the entire BSW Stack
4. BSW Stack Configuration

AUTOMATION!!!
What could be the solution?

Intelligent Configurator Tool
Reduce manual configuration
More reliable

The AUTOSAR Tool Platform (Artop) is an implementation of
common base functionality for AUTOSAR development tools
Advantages for OEM’s and Tier-1’s
Better interoperability of tools that share a common base
platform.
Large user base of common platform ensures higher maturity
and quality of tools
Effort invested into base platform development is spread over
a large community
