MACRO Expansion in Targetlink Code

I am trying to use a unit delay block where the initial condition of delay block is a macro, In the production code of Targetlink the Macro is automatically expanded to the value, i dont want that macro to expand in generated code. The block is inside a Lib file, so the entire code is not generated, only initial values are generated in main code.

Hi Sulagana,
I understand the issue that the macro used to set initial condition of delay block is being expanded in the generated code.
In order to used it as a macro only without being expanded, you can follow below steps:
You can refer this documentation for more info: https://in.mathworks.com/help/ecoder/ug/macro-definitions-define.html

Hi
You could try creating a TargetLink DD variable with MACRO class.
In that case, it should be generated as a MACRO irrespective of the location
