Worked on the lowRISC/opentitan repository to enhance the reliability and maintainability of security-critical OTP memory systems. Addressed unit test failures in the otp_ctrl module by refining timeout handling and alert classification, and templatized assertion logic to improve correctness across different configurations. Developed a feature to dynamically size OTP memory partitions based on actual contents, replacing manual configuration and reducing the risk of partition-size mismatches. Leveraged SystemVerilog for hardware verification and Python for testbench development, focusing on robust memory management. These changes streamlined test workflows, improved validation, and supported faster iteration in production environments requiring high reliability and security.
