name	innovus-command-lookup
description	Look up Cadence Innovus command usage from a local Innovus Text Command Reference, especially when the user asks how to use Innovus commands, options, examples, command order, or related PnR flow commands. Use when files such as innovus_manual.txt, innovus命令手册.pdf, or docs/innovus_flow_commands are available or when the user asks to search the Innovus command manual.

Innovus Command Lookup

Workflow

1. Confirm the working directory and locate the manual assets.

   • Prefer innovus_manual.txt for exact command extraction.
   • Use docs/innovus_flow_commands/*.md for flow context and practical grouping.
   • Treat the PDF as source of truth only when text extraction or Markdown notes are insufficient.

2. For each requested command, first search exact matches.

   • Run rg -n "^commandName$|commandName" innovus_manual.txt docs/innovus_flow_commands from the project directory.
   • If a command name is ambiguous or misspelled, show likely candidates and ask only if guessing would be risky.

3. Extract the command entry.

   • If the repo has tools/extract_innovus_command.py, use it:

python tools\extract_innovus_command.py innovus_manual.txt <command>

• Otherwise use this skill's helper:

python C:\Users\CYL04\.codex\skills\innovus-command-lookup\scripts\lookup_innovus_command.py . <command>

4. Read the relevant flow note when available.
   • 01_design_setup_and_data_io.md: init, import/export, LEF/DEF/netlist, save/restore.
   • 02_floorplan_and_partition.md: floorplan, regions, blockages, PG pins, partitions.
   • 03_power_planning_and_pg_routing.md: global nets, rings, stripes, sroute, low power.
   • 04_placement_and_prects_opt.md: placement, filler/endcap/tap, scan reorder, pre-CTS opt.
   • 05_cts_and_clock_optimization.md: CCOpt/CTS, skew groups, route types.
   • 06_routing_and_postroute_opt.md: NanoRoute, routeDesign, post-route opt.
   • 07_rc_timing_signoff_and_verification.md: RC, timing, signoff, verification.
   • 08_eco.md: ECO placement/routing/netlist edits.
   • 09_non_flow_domains_and_utilities.md: GUI, general utilities, rail, fill, mixed signal.
   • 10_common_commands_detailed_options.md: common option quick reference.

Answer Format

Summarize in Chinese unless the user asks otherwise. Keep the answer practical:

• 命令作用
• 基本语法
• 关键参数
• 常用写法
• 使用阶段 / 前置条件
• 注意事项 / 容易踩坑
• 相关命令

For several commands, use one compact section per command and finish with a short suggested command sequence when useful.

Rules

• Prefer the local manual over memory.
• Do not paste long copyrighted manual passages. Quote only short fragments when necessary, and otherwise paraphrase.
• Mention the source file used, such as innovus_manual.txt or a file under docs/innovus_flow_commands.
• Preserve exact option names and Tcl command spelling.
• If default values matter, verify them from the extracted manual entry.
• If a command is version-sensitive, state that the available local manual is Innovus Text Command Reference 17.11.
