Executive Summary

CANdelaStudio

u CANdelaStudio is an authoring tool:

u specify the diagnostic functionality of an ECU

u Template concept

u guides input of diagnostic data

u guarantees conformity to the OEM specific requirements

u Powerful data exchange features allow to…

u reuse existing data in other formats

u generate data to drive individual processes

u adapt multiple versions of standards (e. g. ODX 2.0.1 and 2.2.0)

u Comfortable user-interface

u short start-up period

u no need to dive into details of diagnostic data modeling and formats like e. g. ODX

u Proven in many car projects worldwide

21/28


Template concept

CANdelaStudio

Diagnostic templateOEM.cddt (XML)

u Combines diagnostic information in a machine-readable CANdela template

Configuration of diagnostics tools

E.g. provide all standard UDS services

E.g. define 3 additional OEM specific services

„Diagnostic Class“ maps services to use-cases: Present Data, Variant Coding, Routine, Fault Memory …

Data Types, DIDs, DTCs, … usable for all ECUs

Attribute definition for ODX export, code generator, validation…

Template concept

CANdelaStudio

u CANdela template

u represents the diagnostic specification for an OEM

u available on request for most known OEMs

u CANdela documents

u are instances of the template

u … for individual ECUs

Why export it?


u CANdelaStudio

u Enables generating diagnostic data

u Focus on diagnostics> No need for special knowledge of the underlying data formats

u Supports import and export of diagnostic data from/to ODX

u Decouples your data from the wide diversity of ODX format conventions > Is therefore ideal for migration of master data to the ODX format

u Many OEMs/suppliers implement consistency in ODX

u Template concept to ensure OEM conforming data

u Quick but stable solution

Authoring Generating Consuming

Data Import and Export

Summary

u Different data formats for different use cases

u CANdelaStudio is capable of generating these data formats

u Imports and Exports can be from standardized formats or customized

u Imports> Standard import features

> Custom import from a database

u Exports> Standard

> CDD -> Vector proprietary data format

> DEXT -> AUTOSAR standard format for code generation

> RTF -> Documentation

> DTC export

> Custom

> ODX (odx-d and PDX) -> Authoring guidelines

> OEM proprietary data format
