Tätigkeitsbeschreibung
Designed and implemented a central safety module, providing a unified safety interface and logic for both Basis and Application software layers, ensuring robust fault detection and response.
Developed a deterministic scheduler bare-metal (without RTOS) leveraging the STM timer, enabling reliable and time-triggered execution of main functions and safety-critical tasks.
Designed and implemented a program flow monitor to supervise software execution paths; integrated its results into the servicing logic of the external watchdog to enhance system reliability and detect latent faults.
Implemented redundant-channel diagnostics and automated safe-state handling for analog, digital, PWM and H-bridge outputs, enabling graceful degradation.
Engineered and realized multiple safe state strategies, enabling selective cut-off of individual I/O channels or groups in response to detected faults, thereby supporting system fail-safety and graceful degradation.
Integrated Infineon SafeTlib with SMU + TLF watchdog and ran start-up/runtime self-tests to meet IEC 61508.
Brought up MCAL-ISAR drivers (ADC, GTM/ICU, SPI, CAN, UART) and created loop-back & fault-injection test suites that validate every analog/digital I/O via CANopen and UART.
