Time to THINK..!
In AUTOSAR eco-system what
are the major challenges
faced by TIER-1s??

Typical Challenges in configuration
Port Connection of Software Components
Data Elements to Signal Mapping
Runnable to Task Mapping

Too many to choose from!

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
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

 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
ProblemsDesirableFeatures

 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
