Why are signals removed from Logic Analyzer?

Hello,
I am working with HDL Coder / Simulink in R2022b, and rely on the Logic Analyzer (LA) viewer to analyze my design as I proceed. I have been completely unable to keep my logged signals from disappearing from the LA view when restarting the simulation. The "log this signal" decorators remain in the design, but nearly each time I click "Run", some or all of the signals I am logging are removed. If I stop logging the signal and restart logging (by clicking the signal and selecting one by one) they will sometimes be added back. But they don't stay there long, making the tool all but unable to be used. Is this a known bug, and is there a plan to fix this?
Thanks,
Eldridge

Thanks for raising the question. As of now you can try unlinking the library block from your model and proceed further with updates within the model. We will get back to you with final resolution.

Has there been any progress on this case? I am still seeing this: failure to add logged signals, as well as missing data for signals in the Logic Analyzer. I am developing using HDL Coder, as we design our IP cores for a Xilinx flow using this tool, so it is very important for me to see signals in the format of Logic Analyzer; the Data Inspector does not work well for this.

Hi Eldridge,
I understand that you are developing using HDL Coder and facing issue with signals disappearing from Logic Analyzer after an update to library.
Your case has been communicated to MathWorks engineers and being looked upon actively. It will be resolved in R2024a release.
