Upgrade Advisor: Check model for Simulink Real-Time logging features
Check ID:
mathworks.design.slrealtimeLoggingUpgrades
This check in Upgrade Advisor checks the model for Simulink Real-Time file logging features from a previous release that require an upgrade for compatibility with the current release.
Available for: R2026a and later releases
Description
This check identifies upgradable Simulink Real-Time file logging features, upgrades
the features where possible, and recommends manual upgrades when needed. Block
forwarding in the slrealtimelib library and the Speedgoat I/O Blockset augments the upgrade process.
Results and Recommended Actions
| Condition | Recommended Action |
|---|---|
Signal upgrades for signals marked (or badged) for buffered logging (in R2020a and previous releases) | Upgrade signals for |
File Scope block upgrades (in R2020a and previous releases) | Upgrade blocks when possible. Identify blocks for manual upgrade when needed. This check requires that the model is in a compiled state. |
File Log block recommendations | Replace detected blocks with an |
After you apply the recommended action for File Scope blocks, the model
Upgrade Advisor offers to create an MATLAB script that creates a file log
Instrument to replace the signals and File Scope
blocks. You run this script to add instruments to your real-time application.
Capabilities and Limitations
You can:
Run this check on your Simulink Real-Time models from release R2025b and previous releases.
