How to force Embedded Coder to unroll the generated for loop of "For Each Subsystem" in generated code?

I am using for each subsystem to simulate and generate the embedded code for embedded hardware.

I have attached the simple example of For Each Subsystem and generated code.

I tried different Code generation Optimazation settings to unroll the loop in generated code but I am unable to solve it.

I tried also different values for loop unrolling threshold but this does not help or may be I am doing something wrong.

Does anyone know how to solve this issue?

Thank you.

Hi @SG,

The code generator unrolls loops when the number of iterations is below the threshold set in "Loop unrolling threshold" in advanced parameters. In the attached "For_Each_Subsystem_Example", there are iterations present in the for loop. Therefore you can set the value for "Loop unrolling threshold" as 4. There are two ways to do this:

• Go to "Code Generation" > "Optimization" > "Advanced Parameters" and set the "Loop unrolling threshold" as 4.

• Use the "set_param" function in command line.

set_param('For_Each_Example', 'RollThreshold', 4)

Here's how the generated code looks like after optimization -
