Hi Matthias Em,
I understand that you have set the Code Generation Identifiers to “GC_$N$M” and would like to have variables names with format “GC_TestSignal” in the generated C code.
The “$N” in “GC_$N$M” refers to the name of the object (block, signal or signal object, state, parameter or parameter object) being identified and in most cases by default “$N” would be the name of the signal itself. However, if the signal name is not provided, "$N" would be the name of the block.
The reason why the name “GC_Multiply4” is being generated is because the signal name is not provided and “$N” in this case would be the name of the block, which is “Multiply”.
Please note that if you are only changing the names of signals and blocks, the code will not be updated after code generation. This is because no structural, parameter, or code replacement library changes would be detected. To reflect the new names, please delete the previously generated code and try generating the code again.
For more information, you can refer to the following documentation pages:
- https://www.mathworks.com/help/rtw/ref/code-generation-pane-symbols.html
- https://www.mathworks.com/help/ecoder/ref/globalvariables.html
I hope this explanation helps and resolves your query about using signal names for variables while generating C code using Embedder Coder.
