Hi Community,
  1. I would like to know if there is any possibility of assigning the custom block names to the variables while the code is generated in simulink.
  2. Also while code is genrated I can see certain variable names are given as rootfile.variableName instead I would like to have rootfile_VariableName.
Any help on this appreciated!
Thanks in advance.

Could you post a screenshot of the generated code? Just the important one?

  1. Take ert.tlc for example, under Code Generation, Identifiers, there are settings that you can change to adjust the Auto-generated identifier naming rules. $N means "Insert name of object (block, signal or signal object, state, parameter, or parameter object) for which identifier is generated."
  2. rootfile.variableName is a structure, not a variable name. It is created for many of the signals that has default properties and auto storae class. To get rid of it, you need to specify properties and storage classes for all the signals within that structure, and set the naming rule as $R_$N (rootfile_ObjectName)

May i know, if there is an options,
  1. to change the inport and outport name in the generated code. right now its coming as X and Y respectively. instead i would like to make those as the blocknames.
  2. in the genrated code what does a block and signal has the impact. My idea is like variable names are the blocks like constants, inport, outport and the signals are pointers or a variable reference to a function?
  3. generated code has intialize, step.. fucntions is there any way i could change the name of those

The best way is to select a signal line, right click, select properties, and then give a signal name and create a signal object. By setting the signal object, you can almost control every aspect of the code generation. Without it, the system starts generating signal names according to the tokens and macros mentoned above.
You can apply this export-function model architecture to specify function name, and use the "Ininialize Function" block. https://www.mathworks.com/help/simulink/slref/initializefunction.html
