Internal Signal logging during SIL Simulation

Asked by Vishakha Bhatia on 11 Jul 2019

Hello All,
Has anyone tried logging internal signals in SIL Simulation?
The suggested C API method from Mathworks is not working in my case.
Regards,
Vishakha

Hi Vishakha,
Are you following the below workflow?
If so, can you confirm that the internal signal of interest is present in the generated code? You may need to mark it as a Test Pointed signal to get it to be preserved.
If a buffer for the signal of interest is preserved in the general code, but SIL internal data is not working, please contact Technical Support and reference this post.
Thanks,
Nick

Hello Nick,
Thank you for the response.
So if i use the c-api method and resolve the signal, it is not present in _cpai.c file.
If I do not resolve it is present and then the signal is also present in the logsout and can be monitored.

Hello Nick,
For R2015b. where for SIL simulation if SIL / PI Lblock is used and not model reference, even if the signal is present in capi.c, it is not present in logs out to be monitored.
I am thinking this is a bug.
