Worked on the lowRISC/opentitan repository to deliver enhancements for SPI device testing, focusing on improving verification fidelity and test reliability. The approach involved configuring SPI device pad attributes for strong drive strength and fast slew rate, which supports more accurate hardware testing and earlier detection of integration issues. Additionally, a lint fix was applied to the BUILD file to ensure clean builds and maintain CI stability. The work demonstrated proficiency in embedded systems, hardware testing, and SPI communication, utilizing C as the primary programming language. These changes contributed to more robust hardware verification workflows and improved the overall development process.
