SimDiff — The only Simulink differencing & merging tool built for real Git and DevOps workflows
SimDiff is the leading solution for integrating Simulink into modern DevOps platforms while minimizing Simulink license usage. Used by virtually every major company building complex mechatronic systems, SimDiff is the only Simulink differencing and merging tool with the accuracy and speed required for native Git workflows—handling models with 30,000+ blocks (which break built-in tools) in under 10 seconds.
Peer Review files let large teams visually review model changes without needing a Simulink license.
Native Git / DevOps ready — Accurate diffs and merges that actually work on large models so your team can use real version control instead of workarounds.
License efficiency — Peer Review files + Automation mean most reviewers never need a Simulink seat.
Speed & scale — Models that take minutes (or fail) in other tools finish in seconds. Proven on 30k+ block models.
Trusted by virtually every major aerospace, automotive, and defense organization building complex systems.
