Model Compare

比较 MathWorks® Simulink®、Stateflow® 和 dSPACE TargetLink模型

Model Compare 可以找出模型的所有更改。即使是大型模型，也能在数分钟内进行对比；但如果没有工具支持，这是不可能实现的。

  • 智能化、可调节的比较算法，带有合并功能
  • 灵活的差分滤波器配置和高度可配置的差分报告生成
  • 具有冲突检测功能和自动解决选项的三向分析

应用领域

当您使用同一模型的多个版本时，自动对比尤为重要。dSPACE 的 Model Compare 可与任何 TargetLink、MathWorks ® Simulink 或 Stateflow ® 模型一起使用，还支持数据库。Model Compare 的使用范围十分广泛，例如：

  • 管理不同模型版本或模型变量
  • 合并平行开发分支版本
  • 验证并审核模型更改

TargetLink 支持

Model Compare 内置对所有 TargetLink 块和属性的支持。它们被按照普通 Simulink/Stateflow 元素的显示和处理方式对待，因此，您无需担心 TargetLink 的实施细节。因为 TargetLink 属性的语义是已知的，因此，可使用预定义的过滤器选项对其进行智能处理。

审核对话与合并支持

您可将审核评论与工具找出的块和属性差异关联，包括日期/作者追踪。支持多个参与者的综合审核。

检测出的更改可以在模型之间传递，以合并平行开发分支版本或管理不同的模型版本。通过易于使用的命令，相较手动合并模型而言，采用这种方法可显著减少出错。始终保持更新模型间的其它差异，因此，您能一直了解工作的当前状态。

与版本控制系统交互

Model Compare可以集成到不同的版本控制系统（VCS）中，包括Git和基于命令行界面的系统。此外，Model Compare可以用于持续集成（CI）管道中，例如用于生成差分报告以便审核。

主要优点

Model Compare 可以找出模型的所有更改。即使是大型模型，也能在数分钟内进行对比；但如果没有工具支持，这是不可能实现的。此外，可选的三向模型分析可以检测到变更之间存在的冲突，并展示模型发生变更的过程，而不仅仅显示它们之间的差异您可使用过滤器重点关注相关差异，并忽略不重要的差异，如布局更改或仿真设置等。对审查会话的支持也可确保对模型更改的可靠、安全且受控制的审核。合并支持简化了对同一模型不同版本的同步更改。

Feature Description Benefit
Support for TargetLink
  • Model Compare recognizes TargetLink blocks and properties, and handles them just like built-in blocks.
  • There is no need to bother with TargetLink implementation details.
Three-way analysis with conflict detection and automatic resolution option
  • Optional analysis of a third (common ancestor) model
  • Option for automatic conflict resolution
  • Detailed information on changes of the models rather than listing only their differences
  • Different model versions can be merged without user intervention
Powerful comparison algorithm
  • Models from different Simulink ® versions are compared; block correspondences are detected even if the names of the blocks have changed; parameter values are compared either in unevaluated form (e.g., “Kp”) or in evaluated form (e.g., “5.4”).
  • Conversion and upgrade problems can be addressed. You get concise comparison results even if blocks were renamed. Different workspace settings can be taken into account.
Flexible filter configuration
  • Model Compare can be configured to filter out unimportant differences, e.g., layout changes or simulation options, according to a variety of criteria. A comparison can be restricted to selected subsystems.
  • You can focus on the differences and model parts that are relevant to you. This greatly improves the efficiency of a comparison.
Convenient result display
  • The comparison results are displayed in synchronized tree views, with differences indicated by customizable color schemes. A statistics window displays the number of changed, added and removed elements.
  • You can easily see which elements correspond to each other. Added, removed and modified elements as well as the number and type of changes can be seen at a glance.
Review support
  • Comments can be associated with individual blocks and properties or with the complete comparison session.
  • Reviews are performed in a reliable, controlled and safe way. You can also use the comment function to structure your own working process.
Traceability from Model Compare to model
  • You can easily highlight Simulink and Stateflow elements by selecting them in Model Compare, and show any differences directly in the compared models.
  • It is easy to view the context of a change and all the differences in a subsystem.
Traceability from model back to Model Compare
  • You can trace model elements in Simulink back to Model Compare
  • This is helpful to identify blocks and lines in Model Compare
Merge support
  • The commands Copy to Right, Copy to Left, and Delete can be used to transfer changes from one model to another.
  • Advanced merge functions for three-way analysis
  • You can merge parallel development branches and transfer changes between distinct model variants.

  • More convenience by automatically merging and resolving conflicts
Report generation
  • Comparison results and associated comments can be saved as HTML, PDF and XML reports, model screenshots can be integrated in the difference reports.
  • The information can be archived and published.
Tool automation
  • Comparisons can be started by command line, and reports can be generated automatically. Reports can be saved in XML format for easy processing by external tools.
  • You can process multiple models automatically and incorporate Model Compare into your own tool chain.
Version control system (VCS) and continuous integration (CI) pipeline integration
  • Model Compare can be integrated in different version control systems, including Git. Furthermore, Model Compare can be used in your continuous integration (CI) pipeline, e.g., for generating diff reports for review pusposes.
  • Work efficiently with numerous model versions. Use established workflows such as a pull request workflow for your Simulink ® models, as known from source file development.
