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

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
