How to implement error port for AUTOSAR receiver interface inport like suggested by Model Advisor check "mathworks​.misra.Aut​osarReceiv​erInterfac​e"

The Model Advisor check "mathworks.misra.AutosarReceiverInterface" throws following warning: "AUTOSAR receiver interface inport does not have a matching error port." with follwowing suggested action: "Add missing error port and map to the corresponding AUTOSAR receiver interface inport."

But how can an error port for a Receiver port be implemented in Simulink? I couldn't find anything in the documentation.

The following steps will remove the warning.

1. Add the required error port to the model.
2. Open the Code Mappings Editor (https://www.mathworks.com/help/autosar/ref/autosarcodemappingseditor.html)
3. For the error ports, set 'DataAccessmode' to 'ErrorStatus' and the Port to the input port that it supports.

I have attached a sample model with this answer.

Hello Jerry,

Could you please give the details with simple example for an input port 'A' and error port adding for 'A'

Hello Jerry,

Could you please share the example to configure this.

Thanks

[Nagaraj Chincholli]

Thanks Jerry for quick response.

Could you please share the 2018b version of example model.

[Nagaraj Chincholli]

Hi,

I am using MATLAB R2018b so unable to open the attached R2021a version 'm_autosar_error_port.slx' file.

Can someone export to R2018b and share me please.

Thank you

[Jerry George]

I have attached an 18a model.

[Nagaraj Chincholli]

Thanks Jerry.

I will look at it.

I followed what is in these 2 links:

https://it.mathworks.com/help/autosar/ug/autosar-communication.html#bsa24_3-6 chapter: Sender-Receiver Interface

and

https://it.mathworks.com/help/autosar/ug/configure-autosar-sender-receiver-communication.html chapter: Configure AUTOSAR Receiver Port for DataReceiveErrorEvent

The error port is simply another simulink input. After you define the input configure it on the Code Mappings Editor as said by Jerry George.
