Generate Parameters as input to step function

I'm not even sure if this is possible anymore. I was working on migrating some matlab models/autogenerated code from 2009->2019a.

It looks like they used to generate a parameters structure with format <modelName>_sl_P that would get passed in as an input to the initialize/step functions. In 2019a, I'm able to generate parameter's into the <modelName>_sl_P structure inside of the <modelName>_sl_data.cpp file.

I'm just wondering if there is anyway to force parameters to be fed in as an input to the step function rather than being accessed globally via includes?

I don't believe this is possible for C++ code gen, but is possible for C code generation. You have to place the parameters in the model workspace and mark them as model arguments as described in this link:
