Simulation Data Inspector is broken

Hey together,

I have installed 2015b (student version) on my laptop. Since a few days the Simulation Data Inspector in Simulink doesn't work anymore. To be precisely, no runs are shown in the window of the inspector despite the fact, that the signals are marked for streaming and the simulation finishes without any error. I wasn't able to figure out any configuration issues which could have lead to this strange behaviour, also it seems to be not an issue with the model. I prepared an minimal model which makes the problem more clear.

The signal "signal" is streamed to the Data Inspector. I run the simulation without problems, but this run is not shown in the Inspector. The Inspector doesn't show any runs at all. However, the Scope shows the signal correctly, so there is no error in the model

Any idea, what I do wrong ?

This seems to be a known bug when the Simulink Data Inspector files get corrupted.

Try typing in the following:

 >> sdi.Repository.clearRepositoryFile

Then, restart MATLAB and try again. Does that work?

Hi Sebastian. This does not seem to solve the issue. Any other suggestions would be highly appreciated!

Thanks, -Ibra

Thanks this just solved my problem. But why is there not error report which suggests this simple step?

Hello,

It seems this bug is supposed to be fixed a long time ago, but I have quite the same behavior in 2023a. Any chance to find a workaround?

Hy Thomas

I have the same behavior with 2023a Update 3. The "sdi" command does not solve the issue in my case.

Regards,

Hi, I'm using matlab 2018a, the SDI is not working even after restarting and clearing repository. Any help would be appreciated!

Just spent several hours on this same issue. The crash report came back as a new bug, but turns out clearing the repository resolves my issues as well. Glad I saw this.

Hello, I try that but I still can't open SDI. Any other recommendation
