Nov 1, 2024November 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.
