I add an information, I notice that the problem comes out if I set CreateSILPILBlock to SIL, while if I use the default value "None", it's ok
Cannot create 'instrumentationInfo.mat' because 'sil\hostobj' does not exist.

hi All, I've got a problem that comes out of nowhere, between two different build session from matlab script. Basically I run my
rtwbuild(systemName);
and I obtain this error:
Error using save Cannot create 'instrumentationInfo.mat' because 'sil\hostobj' does not exist.

I get the exact same error like Maurizio. It popped up out of nowhere between two different builds. I am using Model Reference and have it set up in SIL mode.

Any inputs would be greatly appreciated.

Hi, I also got the same error seemingly from nowhere between two builds. The reason was that I accidentally generated code into a library folder that was used in matlab path. Then for each build, Matlab used parts from that build while building.
So keep your path clean, since matlab will sniff out every bat file and makefile there is!

I had this problem and realized that my Simulink codegen and Simulink cache folders were different, left over from some other codegen. The missing sil\hostobj folder was in the codegen folder.
I set the two folders to be the same, and cleared out both of the slprj folders, and was then able to build.
