S function generation for SIL/B2B testing

Hi,

I have a matlab model and my aim is to perform MIL vs SIL testing/ B2B testing. I am using Matlab 2020a version.( Not using SIL/PIL app mode as of now because not able to handle simulation if I have multiple test vectors signal groups in my signal editor block)

Currently I am generation SIL block by

1) Right click on top level subsystm of model -->Generate C/C++code --> Generate S-function OR

2) Right click on top level subsystm of model -->Test Harness option --> Select SIL option in preopetries block and generate SIL block.

Initially I found mismatches in model and code and I debuggd those and now MIL vs SIL output results are matching.

I knew that using skeleton s-function template file also we can generate SIL block. ( first generate Autocode and then generate S-fun using modified skeleton template file for my model)

According to me there is no functional difference whether we generate s function/SIL block by any way mentioned as above. Can anyone confirm this?

I wanted to confirm my understanding is correct or is there anything I can still check or take care if I am generating SIL block directly.

Also pls suggest which option is useful for generating SIL block for performing B2B testing/ MIL vs SIL testing.

Your reply to my query will be very helpful, Thank you in advance...!
