sch2visio

description

Export the currently active Cadence Virtuoso schematic through virtuoso-bridge-lite and generate an editable Microsoft Visio drawing using the bundled Visio reconstruction workflow. Use when the user says "绘制visio", "画visio", "生成Visio", "schematic to Visio", "sch2visio", or asks Codex to export the current Virtuoso schematic into Visio from `netlist.cdl`, `inst_info.txt`, and `wires.tsv`, or wants to validate and draw Visio directly from existing export artifacts on Windows.

Sch2Visio

Overview

Run the full current-schematic pipeline: execute the remote Virtuoso SKILL exporter, download netlist.cdl, inst_info.txt, and wires.tsv, then call the bundled Visio wrapper to validate and draw the schematic in Visio directly from those files.

Quick Start

When the user says "绘制visio" with no extra details, run:

python <path-to-sch2visio>\scripts\sch2visio.py

Default assumptions:

• The target schematic is open and active in Virtuoso.
• virtuoso-bridge start is already running and the bridge setup is loaded in CIW.
• A remote sch2visio.il exporter entry point exists on the Cadence host.
• Local workspace contains virtuoso-bridge-lite, or pass --bridge-root.

Bundled Resources

• Full export-and-draw runner:
  • scripts/sch2visio.py
• Direct Visio wrapper for existing artifacts:
  • scripts/run_cadence_to_visio.py
• Bundled project code:
  • scripts/project/cadence_to_visio_v2.py
  • scripts/project/cadence_to_visio_core.py
• Bundled assets:
  • assets/visio/circuit.vss

Common Commands

Use an explicit local output directory:

python <path-to-sch2visio>\scripts\sch2visio.py `
  --local-dir C:\path\to\output\SA_PreCh_visio

Use a custom remote export directory:

python <path-to-sch2visio>\scripts\sch2visio.py `
  --remote-dir /tmp/SA_PreCh_export

Forward native cadence_to_visio_v2.py options after --:

python <path-to-sch2visio>\scripts\sch2visio.py `
  -- --skip-nets vdd,vss --skip-mos-body-nets

Run export/download/validation without opening Visio:

python <path-to-sch2visio>\scripts\sch2visio.py --validate-only

Validate existing exported files without running the remote Virtuoso export:

python <path-to-sch2visio>\scripts\run_cadence_to_visio.py validate `
  --wires C:\path\wires.tsv `
  --netlist C:\path\netlist.cdl `
  --inst-info C:\path\inst_info.txt `
  --cwd C:\path\output

Run the bundled Visio reconstruction directly:

python <path-to-sch2visio>\scripts\run_cadence_to_visio.py visio `
  --wires C:\path\wires.tsv `
  --netlist C:\path\netlist.cdl `
  --inst-info C:\path\inst_info.txt `
  --cwd C:\path\output `
  -- --skip-nets vdd,vss --hidden

Outputs

The runner creates these local artifacts:

• netlist.cdl: downloaded CDL from Virtuoso.
• inst_info.txt: downloaded instance placement/orientation file.
• wires.tsv: downloaded wire coordinates.
• schematic.vsdx: saved Visio drawing when Visio generation succeeds.

Troubleshooting

• If SKILL execution blocks on a Virtuoso dialog, run virtuoso-bridge dismiss-dialog, then retry.
• If the runner cannot import virtuoso_bridge, pass --bridge-root C:\path\to\virtuoso-bridge-lite.
• If Visio generation fails after validation, verify Microsoft Visio and pywin32 are installed.
• If wire validation fails, inspect the downloaded wires.tsv header; it must include group_id, seg_id, net, obj_type, layer, purpose, x1, y1, x2, y2.
• For exact input contracts and forwarded options, read references/inputs-and-workflow.md.
