Worked on the OpenXiangShan/XiangShan-doc repository to enhance project documentation and streamline tooling outputs. Focused on updating the xsenv tool’s documentation, the developer aligned generated Verilog outputs with SystemVerilog conventions by changing file extensions from .v to .sv and reorganizing output files under a dedicated rtl subdirectory. This adjustment improved automation and maintainability for downstream workflows. The work was carried out using Markdown for documentation and involved a clear understanding of hardware description languages and project structure best practices. Over the course of one month, the developer delivered one feature, emphasizing clarity and consistency in technical documentation and tooling processes.
