Check model version consistency between generated code and model

Hello experts,

a Simulink model is equipped with a "Model Version", which is increased every time a change in a model is saved. We can read this from the model via

get_param(model,'ModelVersion')

If we generate code from this model, the *.c and *.h files also include this model version, e.g.

* Code generated for Simulink model 'FeatureName_GENCODE_mdl'.
 *
 * Model version                  : 1.44
 * Simulink Coder version         : 9.8 (R2022b) 13-May-2022
 * C/C++ source code generated on : Tue Feb 27 07:46:12 2024

Is there an option, to retrieve the model version from generated code programmatically, to check the consistency of model versions between generated code and model (despite performing SIL/PIL tests)?

To manually parse generated C-Code in MATLAB and search for Model version seems a bit unclean to me. Is there a better option?

Many Thanks and BR!

I do not think the Model version is available, however, you can use get_param(model,'ModelVersion") from the model, and then compare the checksums for the model and generated code to confirm that the code is from the current version of the model:

To get model checksum:

Simulink.BlockDiagram.getChecksum(model)

To get checksum for generated code:

Navigate into the code generation directory

load codeInfo.mat

codeInfo.Checksum

If the two checksums match, then the generate code is from the current version of the model.

Thank's for this hint! Checksum is much better than version.
