安路 FPGA 代码设计 skill。Use when: 需要把已分析清楚的需求落成一致风格的 RTL，规范接口、简化 primitive 引脚连接、保持可扩展可移植，并形成交给 anlogic-testbench 的设计交付。
安路 FPGA bitstream 生成 skill。Use when: 需要执行、排查或审阅 TD 的 bitgen、setup_debugger、export_bitgen_param、export_bid，确认从已放行的 pr.db 到 .bit/.bid/.bitgen_param.f 的边界、输入、交付物和放行条件，判断问题属于 bitgen 参数、前置 pr.db、probe/debugger 还是文件/权限，并避免把 route 或下载交付误塞进 bitstream 阶段。
Use when Anlogic FPGA verification inputs are ready and Codex needs to run ModelSim, organize `run.do` plus `wave.do`, preserve waveform artifacts, export `.vcd` from `.wlf`, and produce a pass/fail/block conclusion that is valid for downstream waveform extraction and signal comparison.
Use when Anlogic FPGA work still needs requirement decomposition, device and resource judgment, interface analysis, module partitioning, timing/data-flow planning, or upstream design direction. This stage must decide when the requirement is clear enough to hand off either to `anlogic-python-signal-pre-research` for a reference timing baseline or to later specialist Anlogic skills.
安路 FPGA 布局布线 flow skill。Use when: 需要执行、排查或审阅 TD 物理实现阶段的 opt_place、opt_route，确认从 gate.db 到 pr.db 的边界、输入、交付物和放行条件，判断问题属于 place、route、hold 修复、时钟/拥塞/DRC，避免把综合问题或 bitgen 交付误塞进物理实现阶段。
Use when Anlogic FPGA verification is already complete and Codex needs to create the TD project from validated design inputs, constraints, IP, and wrappers. This stage begins only after `anlogic-modelsim`, `anlogic-wave-signal-analyzer`, and `anlogic-signal-comparison` have produced a clean release conclusion.
安路 FPGA 综合 flow skill。Use when: 需要执行、排查或审阅 TD 综合阶段的 read_design、opt_rtl、opt_gate，确认综合阶段的输入、边界、交付物和放行条件，判断问题属于工程入口、RTL/IP、约束还是 primitive 映射，并避免把 place、route、bitgen 的等待和动作误塞进综合阶段。
安路 FPGA testbench skill。Use when: 需要消费 anlogic-code-design 的设计交付，生成 stimulus、monitor/checker、期望结果和通过判定口径，并把可运行输入交给 anlogic-modelsim。
