PROFILE

Yaozhicheng

Zhicheng Yao developed and maintained the XS-MLVP/UnityChipForXiangShan repository, focusing on backend infrastructure, build automation, and documentation standardization over six months. He implemented modular Python-based build systems, streamlined RTL workflows, and enhanced CI/CD pipelines to reduce feedback cycles and resource usage. Yao introduced robust configuration management and multi-level logging, improving debugging and deployment reliability. He also established governance-first documentation, onboarding guides, and Docker-based development environments to support contributors. Leveraging Python, Shell scripting, and YAML, his work addressed both technical depth and process quality, resulting in a more maintainable, accessible, and collaborative codebase for hardware verification and development.

Nov 1, 2024

November 2024 performance summary for XS-MLVP/UnityChipForXiangShan: Delivered Toffee integration with constants, module rename (mlvp -> toffee), and dependency installation setup, enabling Toffee-based reporting. Fixed RTL download flow to ensure correct behavior. Revamped configuration management with refined cfg, moved report args to cfg, added new_report_name, refined defaults, and introduced noskip. Added multi-level logging for improved observability. Migrated the build system from Makefile to Python, stabilized DUT build targets (build_dut prefix and removal of dut_all), and tightened build/test infra (including test result JSON export and extended documentation). These changes collectively reduce deployment risk, shorten CI cycles, and improve configurability and telemetry for customers.
