bb-find-module-deps

职责

扫 designs/<name>/rtl/*.sv,构建 module → file 映射 + module instantiation 图,Kahn 拓扑排序,写 file_list.f。

  • 调用者:bba-guru-rtl
  • 下游:bb-check-lint、bb-invoke-yosys、bb-invoke-verilator
  • 禁止使用:Task / Agent / Skill

4-Phase 执行

Phase 1 — render_filelist_py

scripts/render_filelist_py.py 生成 Python:

# 优先用 verible-verilog-syntax 解析(识别 interface/class/package 与 module,避免误判 — fix M-04)
# 失败时退到正则 fallback
try:
    import subprocess, json
    out = subprocess.check_output(["verible-verilog-syntax", "--export_json", f]).decode()
    ast = json.loads(out)
    # 遍历 ast 找 ModuleDeclaration nodes
except Exception:
    # fallback: 正则 `^\s*module\s+(\w+)` + 排除 interface/class/package 关键字
    pass

# 然后建 dep 图:parent_module → set(child_module)
# Kahn 拓扑(child 先 parent 后);检测环
# 写 file_list.f:incdir / define / 拓扑序文件

Phase 2 — run_filelist_gen

scripts/run_filelist.py:timeout 180 uv run python <script_path> > <log> 2>&1

Phase 3 — parse_filelist

scripts/parse_filelist.py:

  • 验证 file_list.f 存在
  • 验证 top_module 对应文件是最后一个
  • 计数 module_count
  • log 含 Cyclic dependency → error="cyclic: A->B->A"

Phase 4 — return

返回 JSON。bba-guru-rtl 直接把 artifact_path 传给下游。

file_list.f 格式

+incdir+designs/<name>/rtl/include
+define+TARGET_ASAP7
designs/<name>/rtl/uart_fifo.sv
designs/<name>/rtl/uart_rx.sv
designs/<name>/rtl/uart_tx.sv
designs/<name>/rtl/uart_ctrl.sv
designs/<name>/rtl/uart_top.sv

收敛 / 失败

状态行动
valid=true进 bb-check-lint
cyclic开 arch-needs-fix(模块循环必须重设计)
找不到 top_moduleerror="top not found",bba-guru-rtl 修正
