SystemDesk

仿真和验证的起点

SystemDesk是软件在环（SIL）过程的理想基础。基于现有的ECU代码，您可以创建虚拟ECU，并能够在经济高效的SIL仿真中执行和测试代码。如果您想为新的Classic AUTOSAR架构建模或修改现有的AUTOSAR架构，SystemDesk提供了功能强大但易于使用的AUTOSAR架构工具。

为SIL测试创建一个有效且真实的被测系统（SUT）

V-ECU 是一种可以在SIL环境中执行的ECU软件。V-ECU可以基于Classic AUTOSAR、非AUTOSAR兼容代码、Adaptive AUTOSAR，甚至POSIX应用程序。SystemDesk为创建用于SIL测试的V-ECU提供完全支持。

在classic AUTOSAR环境中，V-ECU可以包含待测试功能的产品级代码，但是仅在应用程序级别，或者包括基础软件。我们可以创建V-ECU，其包括应用程序软件和基础dSPACE软件，也可以使用您自己的基础软件。通过使用基础的dSPACE软件，您可以快速轻松地创建V-ECU，而无需对AUTOSAR有深入的了解，即可集成您自己的基础软件，让真实的虚拟ECU仿真您的真实ECU。不符合AUTOSAR的代码也可以作为经典V-ECU的基础。这是通过输入功能、它们的周期时间和接口来完成的。 V-ECU 甚至可以使用基础软件为非AUTOSAR ECU创建。

除了传统环境中的V-ECU之外，V-ECU还可以基于动态响应架构。这包括POSIX应用程序和 Adaptive AUTOSAR ..Adaptive AUTOSAR具有不同的架构，其中运行时环境独立于应用程序级别（中间件）进行使用。因此，应用程序可以灵活地交换和更新，同时仍使用AUTOSAR标准化的中间件功能。对于V-ECU，您可以使用自己的中间件或AUTOSAR Adaptive Platform Demonstrator中的中间件。

您可以使用VEOS来仿真完成的V-ECU，从而在基于PC的仿真中验证您的软件。当然，这也适用于 来自适应环境的 基于Linux的V-ECUs利用ControlDesk等实现软件，您可以对结果进行评估。

您是否在软件中定义了要更改的行为？只需在SystemDesk中加载您的软件架构，即可更改必要的组件或调整C代码。再次生成V-ECU后，您可以直接用VEOS检查更改的结果。获得快速有效结果的捷径。

用于测试的理想V-ECU

在实现真实ECU的过程中，在开发过程结束时，SystemDesk在应用程序、仿真BSW和产品级BSW级别支持V-ECU。

Application-Level V-ECUs

Application-level V-ECUs can be used to perform comprehensive functional testing on application software. Both individual software components and a complete application software can serve as the basis for the V-ECU. Even at this initial level, the V-ECU can be used within a continuous testing process to detect errors early on in the development process.

Simulation BSW V-ECUs

In addition to the first level, the second V-ECU level includes non-productive basic software that was created only for this specific V-ECU and its simulation. Thus, the V-ECU can be connected to a virtual bus and tested in a broader context.

Production BSW V-ECUs

In addition to the application software, production BSW V-ECUs also contain the productive basic software. Thus, they simulate the hardware-independent software of the real ECU. Because these V-ECUs are suited for complete ECU software tests, they are often used by ECU managers in HIL frontloading.

Modeling Your Software Architecture

Create your own AUTOSAR software architecture from scratch or enhance an existing architecture.

SystemDesk offers comprehensive modeling tools. For example, you can create individual or multiple software components down to the last detail before combining them into an integrated composition. As a result, it is possible to model the entire application layer of an individual ECU or even application software spread out across multiple ECUs.

The modeling of a classic AUTOSAR architecture is supported in SystemDesk by intuitive preconfigured dialogs to maintain an overview of your model at all times. The comprehensive graphical support not only helps you use the product for the first time but also promotes efficient work with reduced errors in large-scale projects. 

In such large-scale projects, AUTOSAR files are usually stored centrally in a version management system, such as git, so that various developers and architects can work separately and in parallel. If any conflicts arise or if you simply want to obtain a quick overview of any changes, dSPACE AUTOSAR Compare supports you completely independently of your other tools. Combined with SystemDesk, you can even display the differences between a specific file and the current project state in SystemDesk.

To improve the quality of the projects, SystemDesk includes a function for the comprehensive, rule-based validation of consistency and correctness.You can validate both the entire architecture and individual components or elements from the dialogs.

To provide even more comfort, SystemDesk can help you automate recurring tasks. An advanced API allows for a high level of automation using simple Python scripts.

进入SIL仿真世界

基于软件架构，您已经使用SystemDesk创建了一个V-ECU：这标志着您进入了灵活且经济高效的软件在环仿真世界。基于V-ECU的可延展性，您可以节省花费在HIL测试上的时间，同时运行不同的测试，甚至可以直接在开发人员PC上执行测试。Level-1的V-ECU甚至可以在SCALEXIO上作为残余总线使用。

除了可以轻松地将SystemDesk集成到现有的工具链中之外，dSPACE还提供兼容的产品来优化SIL中的工作流程。例如，您可以在VEOS中仿真一个或多个V-ECU，并在真实环境中进行测试。利用ControlDesk，您可以在简明的概述中评估所有值，而通过AutomationDesk，您可以完全自动地运行测试。

AUTOSAR文件可以集中保存，不同的开发人员和架构师可以从所有这些产品中并行地访问它们，例如在git等版本管理系统中。如果出现任何冲突，或者您单纯想快速了解更改，dSPACE AUTOSAR Compare能完全独立于其它工具对您进行支持。
