IBIS-AMI model creation errors on Linux

Hi All,

I have a SerDes Designer project in Simulink. I want to compile it and create/export the corresponding IBIS-AMi model for the TX. The process works ok in Windows, but not in Linux, where it ends with some error messages, as reported here below:

### Model failed to compile with strict bus check on

### Turning strict bus check off

Error using coder.build.internal.buildSubsystem

Model has compile errors.

Error in coder.build.internal.buildSubsystem

Error in slbuild

Error in slbuild

Error in rtwbuild

Error in serdes.internal.rtwbuildWrapper

Error in IbisAmiManager/ExportButtonPushed (line 831)

Error in appdesigner.internal.service.AppManagementService/executeCallback (line 172)

callback(appOrUserComponent, event);

Error in matlab.apps.AppBase>@(source,event)executeCallback(ams,app,callback,requiresEventData,event) (line 62)

newCallback = @(source, event)executeCallback(ams, ...

Caused by:

Error using coder.internal.RightClickBuild/compileModel

Unable to create mex function 'b68s_tx_deemp_sfun.mexa64' required for simulation.

Error using appdesservices.internal.interfaces.model.AbstractModel/executeUserCallback

Error while evaluating Button PrivateButtonPushedFcn.

I tested with no success 2 different Matlab versions: R2024a and R2023b. Moreover I got the same identical error with a different serdes project, so this seems to be an issue/bug related the tool configuration, but not to my specific project.

The MEX building tool seems to be correctly configured:

>> mex -setup c++

MEX configured to use 'g++' for C++ language compilation.

>> !which gcc

/bin/gcc

>> !which gmake

/bin/gmake

My Linux version is RedHat 8.

Hi,

I encountered a similar issue while working with the SerDes Toolbox in Simulink when compiling my Tx model. Here is a workaround that I used, which might help resolve the problem:

1) Load a Blank Model: Open a new blank model in the SerDes Designer. This model should compile without any issues.

2) Export and Copy Configurations:

a. Export this blank model to Simulink.

b. Use the ‘Model Explorer’ to copy the configuration settings from this blank model.

3) Apply Configurations to Your Model:

a. Open your original model that is causing the error.

b. Paste the copied configurations into your model using the ‘Model Explorer’.

4) Export the AMI Model: Try exporting the AMI model again.

5) Adjust the Stimulus Block:

a. If the error persists, locate the "stimulus" block in your model.

b. Check the 'custom stimulus' option and enter `[0 1 0]` as the value.

c. Uncheck the 'custom stimulus' option.

6) Export Again.

This workaround addresses issues related to configuration parameters, which appear to be the root cause, especially since the problem persists even with default SerDes Toolbox blocks. If the issue continues, consider reaching out to MathWorks support for further assistance.

Hope this helps!
