Autosar code generation error in R2020b
I want to migrate a model from R2017b to R2020b, when I generate the code in R2017b I don’t have any issues, nevertheless the same model with the same configuration on R2020b returns the following when I try to generate code:

This seems to be a known issue, comes from a bug before R2020b, which prevents the code generation in the latest release. For a workaround, do the following steps:
- In R2020b, open Model Explorer under the Modeling tab.
- In the Model Hierarchy, search for the Functions or Truth Tables that are defined inside of a Stateflow chart as in the following example:
- Select “Inline” instead of “Auto” in Function Inline Option on the right section of the page
- Click Apply and Ok
