Rte Explicit Read inside if condition

Dear all

could you please help me with the following problem?

I have to to an Rte Explicit read (AUTOSAR) port inside an if block. I've tried several solutions (enabled sub-systems, if action, function call) but it generates the code with the Rte read in the if condition, but it adds another variable that I don't want in the final code.

Then at the end I need a code like this:

if (condition){
Rte_Read_XXX(&tmp);
}

But what I tried generates the following code:

if (condition){
Rte_Read_XXX(&tmp);
Var = tmp;
}

and then uses Var. I don't want it to create this additional variable.

NOTE: I'm using MATLAB 2016B and Embedded Coder.

Hey

The issue arises because when using 'ExplicitReceive' mode, Simulink automatically buffers the data to ensure simulation and code behavior match. This often results in an additional variable in the generated code.

You can refer to following links for more infromation:

Their is a MATLAB answer about a similar topic on Rte_Write.
