For hyper-realistic software-in-the-loop (SIL) simulation of ADC and ePWM behavior in Simulink without using actual hardware or generating firmware-ready code, the C2000 Microcontroller Blockset is the most direct and reliable solution. It has many uses as mentioned below:
- Provides peripheral blocks like ADC, ePWM, Digital I/O, Hardware Interrupt, etc., that accurately model TI C2000 behavior in Simulink.
- Supports ADC–PWM synchronization with examples showing interrupt-driven interaction and callback behavior.
- Works entirely in Simulink (SIL) mode—no hardware or firmware generation needed.
To set it up follow the below steps in detail:
- Install and enable the C2000 Microcontroller Blockset in your Simulink library.
- Drag in ADC and ePWM blocks from the TI C2000 library.
- Configure interrupts using the "C28x Hardware Interrupt" and ADC "Interrupt blocks" to model nested priority behavior or trip logic.
- Connect ADC and ePWM blocks to your control logic; simulation will reflect timing and sampling behavior closely.
