Why am I getting a "Code generation assertion 'inportNam​esToPropsM​ap.find(ar​gName) == inportName​sToPropsMa​p.end()' failed"?

Hi all,

I am trying to generate C++ code for a Simulink model using the Embedded Coder. The model is able to compile and run in Matlab R2021b, but when I generate the code I get the following error:

Code generation assertion 'inportNamesToPropsMap.find(argName) == inportNamesToPropsMap.end()' failed in 'B:\matlab\src\slcg_buffer_reuse\analysis\reusable_csc_utils.cpp:2027'

I am not sure what the error could relate to.

Can you copy your model, then remove as much as possible while still having this error happen? If the error goes away, it may help you solve your problem. If not, perhaps the simpler model can be posted here for the Community to help.

I attach the model here

The model in question is SupervisorFSM_RX.slx. To be able to use the model you must first run update_dictionary.m, and have all the other files in the matlab path.

If you compile (for example by pressing Update Model) it works, but when using the Embedded Coder you should get the error.

Hi German Rodriguez,

I understand that you are facing an error while generating code using Embedded Coder for a Simulink model.

Code generation assertion 'inportNamesToPropsMap.find(argName) == inportNamesToPropsMap.end()' failed in 'B:\matlab\src\slcg_buffer_reuse\analysis\reusable_csc_utils.cpp:2027'

The error could be because of potential conflicting usages of identifier 'arg_Input': a global identifier from 'C++ class interface', and a global identifier from 'C++ class interface'.

This conflict may be resolved by either increasing the maximum identifier length on the Identifiers pane of the Configuration Parameters dialog box or by changing the name of the conflicting identifier.

Hope this helps and solves your error!
