Hello, I've successfully tested the Processor-in-the-Loop (PIL) workflow in Simulink using a TI F28069M LaunchPad, following the standard examples provided by MathWorks. The PIL block, code generation, and communication all worked without issues. Now, I’d like to run a similar PIL setup using the Infineon TLE9879 EVALKIT (based on an ARM Cortex-M0), which is not officially supported by Simulink as a target. I’m wondering if it’s possible to configure PIL manually or via custom workflows. For example: Can I create a custom PIL target using Embedded Coder? Would I need to port rtiostream manually for communication over UART? Could I somehow integrate with Keil µVision (which I use for TLE9879) to build and run the generated code? Is there a workaround to simulate PIL behavior using a non-supported board? My setup: Simulink R2024b Infineon TLE9879 EVALKIT Keil µVision 5 + Infineon Config Wizard UART and JTAG interfaces available The main purpose is to validate control algorithms and measure execution time, not to implement a full HIL system. Has anyone attempted PIL with a custom or unsupported microcontroller before? Any tips or resources would be greatly appreciated. Thanks in advance! Is it possible to run PIL in Simulink with a non-supported microcontroller like Infineon TLE9879? simulink pil
