CANdelaStudio - Efficient Specifying of Diagnostic Data
The specification tool CANdelaStudio is a central component of the Vector CANdela solution and supports users in creating and editing a formal vehicle ECU diagnostic specification.
Once a diagnostic specification has been created, it is used for the following process steps and increases thereby the consistency in the entire diagnostic development process:
- Implementing the diagnostic software
- Automated conformity tests of the diagnostic software
- Data supply for the various diagnostic testers in development, manufacturing and the service garage
- Starting point for test sequences in diagnostic testers in production and the service garage
Data exchange regarding import from ODX (2.2, 2.0.1) and export to ODX (2.2, 2.1, 2.0.1) as well as the migration of diagnostic data to ODX is perfectly supported.
Advantages
- The user is guided by a templates concept. Despite differences in requirements, the diagnostic data is always described in a similar structure, even for different automotive OEMs. This enables reusability across projects.
- Consistency checks during input assure high data quality.
- Diagnostics-oriented user interface assure quick results.
- Import and export from/to different exchange formats (ODX, AUTOSAR DEXT, CSV, RTF, HTML, A2L, XML, CDI) simplify reuse and further use of data
- Support of different protocols on different networks (UDS, KWP2000, OBD, WWH-OBD, CAN, LIN, MOST, FlexRay, DoIP)
Functions
In order to handle OEM-specific differences in a single tool, CANdelaStudio supports document templates. A document template corresponds to an OEM-specific diagnostic specification in content. It contains a formal description of all allowable basic services of the ECU and the set of mandatory content that must be implemented for every ECU. Document templates are provided by many automo-tive OEMs.
- Comparison view: Shows changes between two versions and saves the results. Many convenient filter, search and extended navigation functions are offered.
- Import and export of diagnostic trouble codes (DTCs) in a wide variety of formats
- Different views of diagnostic trouble codes: From a table-based overview to a view of the validity of DTCs in different variants and a detailed editing view for an individual DTC.
Highlights Version 13
AUT0SAR Adaptive
- Simply activate AUTOSAR support in the document properties
- Select AUTOSAR Classic or Adaptive and also the AUTOSAR version for the DEXT export
AUT0SAR: Fault Memory Optimization
- Snapshot Records and Extended Data Records are defined for each fault memory diagnostic instance with specific AUTOSAR properties.
- Compliant with AUTOSAR: Snapshot Data (DIDs) are now identical for all Snapshot Records.
- Supported AUTOSAR detail properties:
- Trigger: defines the time when the DEM module should save the Snapshot Record.
- Update: defines whether the module overwrites already stored Snapshot Data.
- Alternatively, define only the number of Snapshot Records to be stored (“Calculated”)
- For individual DTCs you can prevent single records from being saved
Compare View
- The new version 13 now allows to edit or change documents while the Compare View is open.
- Refresh the Compare View simply by a click of a button after changes have been made.
Further Optimizations
- Simplified synchronization of DIDs and diagnostic instances
- Updated Vector UDS Template: UDS Service 0x29 and DTC Properties
- Many optimizations on the user interface
Data Exchange and Reports
ODX
- Import from ODX (2.2, 2.0.1), as well as export to ODX (2.2, 2.1, 2.0.1)
- Extensive optional settings in ODX export (e.g. table or service oriented)
- Partial import of ODX data, e.g. only Layers and Services
- ODXStudio View for viewing ODX data
- Intelligent support of Object IDs (OID) and Text IDs (TID)
AUTOSAR
- Simple import of signals and conversions from an AUTOSAR System Description
- Export function for generating the AUTOSAR Diagnostic Extract (DEXT files). The exported files correspond to the “Diagnostic Extract Template” standard of AUTOSAR 4.2.2/4.3.0.
- Automated linking of CANdela objects with the corresponding objects in the AUTOSAR System Extract
(SYS-EX)
CANdb and FIBEX
- Adoption of signals and conversion into data objects and DTCs
Reports
- Diagnostic specification export (RTF, HTML)
- Service overview export (CSV file)
Editions
CANdelaStudio Standard offers all important functions to conveniently describe ECU diagnostics (e.g. ECU identification, fault memory, session, security, ...).
Functions of the edition "Standard":
- Creating and editing CANdela documents (*.cdd) using CANdela templates (*.cddt)
- Setting attribute values for code generation, for example
- Comparing two CANdela documents, or parts of CANdela documents
- Importing data from various standard formats (ODX, CSV, …)
- Exporting the CANdela document to various data formats
- Viewing and consistent editing in one language
Target group: All active participants in the diagnostic process should use CANdelaStudio Standard.
The well-priced CANdelaStudio ViewX edition provides viewing, comparing and exporting of diagnostic data, but no editing.
- It has the same functionality as the View Edition, which is delivered with the Vector Tools (CANoe, CANape...) and can export the diagnostic specification as a requirement specification (RTF, HTML).
- Additionally, it features data oriented exports (ODX, CVS…), a compare view and an ODX Viewer.
Target group: Authors of test sequences and users of test systems.
Like CANdelaStudio Standard, additionally with manual and semi-automatic translation of the diagnostic specification into multiple languages (in the Standard Edition, you consistently edit the diagnostic specification in one language only).
Furthermore, you can create and use dictionaries following the open TMX standard. Besides Western European languages, Far Eastern languages like Japanese are supported.
Target group: International projects and projects where multilingual specifications are required or helpful.
Like CANdelaStudio Pro, with additional editing of diagnostic templates (*.cddt) for the definition of:
- Fundamental Protocol Services
- Fault Memory (structure and properties of individual diagnostic trouble codes)
- Diagnostic Classes for different diagnostic use-cases
- Specifying authorization settings for objects
- Modifying objects without restriction by authorization settings
- Attributes for configuring diagnostic tools (tester, code generator, validation…)
- Delete individual revision entries
Furthermore, you can edit template aspects in CANdela documents (*.cdd) and translate templates (*.cddt).
Target group: Users who are responsible for the global diag-nostic concept of a group of ECUs or vehicle model series.
