Version Control System Integration
SimDiff integrates with many version control systems (VCSs) and we provide articles detailing the setup process: ClearTeam Explorer, Git, Git+Git Extensions, Git+SourceTree, Mercurial, TortoiseGit, and TortoiseSVN. If you have questions about the existing documentation, or if your version control system is not listed, please contact ENSOFT support.
DevOps Integration
We also offer documentation to integrate SimDiff Automation into your DevOps workflow, using Azure DevOps, GitHub, and GitLab as examples.
System Requirements
SimDiff supports all Windows versions going back two decades and common Linux versions. SimDiff can compute differences without MATLAB/Simulink installed, though some advanced features do use it. SimDiff supports R2007b and higher, all the way up to the most recent release. Full SimDiff System Requirement details can be found here.
