Tool Mentor: dSpace SystemDesk Timing Extension Editor
SystemDesk Timing Extension Editor is a SystemDesk addon especially developed to store system timing information along with the system model as specified in the AUTOSAR timing extension (4.0.3).
As specified by the standard AR4.0 Rev3, the editor allows the user to specify/define the timing information at various abstraction layers, i.e., Vfb timing, Swc timing, System timing, Bsw Module timing, and Ecu Timing.

Main Description

Abstraction level

Implementation

Use Case Tasks

·         Specify timing information according to AUTOSAR 4.0.3 standard

Covered aspect

The SystemDesk Timing Extension Editor (SDTEE) allows specifying the timing information as described by the AUTOSAR 4.0.3 timing extension standard. The timing information can be specified at various abstraction layers, i.e., Vfb timing, Swc timing, System timing, Bsw Module timing, and Ecu Timing.

Algorithm

Manually entering of timing information linked with AUTOSAR system model

Inputs

Vfb and Swc timings only require software architecture in SystemDesk. For System, Bsw Module and Ecu Timings require complete system design model.

Particular constraints on inputs

The defined model in SystemDesk must comply with AUTOSAR 3.x standard in order to specify the system timing information **.

The timing information available in EAST-ADL design model must firstly be transformed manually to meet the AUTOSAR 4.0.3 timing extensions. The transformed timing information can further be decomposed using SDTEE.

**Since the particular tool is a prototype, therefore at the moment can be used with SystemDesk 3.1.

Preparation of input

Load AUTOSAR system design in SystemDesk i.e.,*.sdp file, workspace

Invocation of the algorithm

Open SystemDeck Timing Extension Editor from SystemDesk “View” menu to specify the timing events, event chains, and constraints (requirements and guarantees), at various abstraction layers, i.e., Vfb timing, Swc timing, System timing, Bsw Module timing, and Ecu Timing, in the design model

Outputs

AUTOSAR Timing Extension file i.e.,*.arxml file, listing the overall system timing information as specified by AUTOSAR 4.0.3

Visualization of results

By selecting the entries, i.e., event or event chain, in SystemDesk Timing Extension Editor tree view the SystemDesk highlights the corresponding port or path in its graphical user interface (the particular feature is under development)
