PROFILE
Sharon Topaz
Contributed to the lowRISC/opentitan repository by developing enhancements for SPI device testing and expanding the flexibility of register abstraction layer (RAL) workflows. Leveraged SystemVerilog and Python to configure pad attributes for improved SPI verification and implemented environment variable handling to support vendor-specific configurations. Extended memory backdoor data width to increase test coverage and reliability, while addressing a bug to prevent unintended object mutation in Python scripts. The work emphasized robust hardware verification, code refactoring, and configuration management, resulting in more reliable CI processes and enabling earlier detection of integration issues in embedded systems and hardware design environments.
