Developed a standalone watchdog timer feature for the chipsalliance/caliptra-mcu-sw repository, focusing on enhancing the emulator’s MCI peripheral. The work introduced support for two independent watchdog timers, each with enable, control, and timeout capabilities, improving the robustness of hardware emulation. Leveraging Rust and system programming skills, the implementation included scheduling of watchdog expirations and real-time updates to status registers to accurately reflect timer states. Comprehensive test coverage was added to verify correct watchdog behavior and prevent future regressions. The emphasis on embedded systems and hardware emulation ensured the new feature integrated seamlessly and improved the reliability of the emulator.
