Import P&R (Genus + Innovus) products into Virtuoso: GDS layout, Verilog schematic/symbol, power labels, and label restyling. Four-step pipeline driven entirely from vcli skill exec — no Python bridge or GUI required. Use when: (1) user wants to pull a routed GDS or post-P&R netlist into Virtuoso, (2) layout labels look giant/unreadable after import, (3) user mentions strmin / ihdl / digital import / P&R-to-schematic flow.
Generate Virtuoso schematics from topology descriptions via vcli schematic commands. Use when: (1) user wants to draw/create a schematic in Virtuoso, (2) user says "draw the OTA" or "create the schematic", (3) after sizing is complete and ready to build the circuit, (4) user provides a topology and wants it instantiated.
Read Maestro/ADE simulation output values directly from PSF binary files — no Virtuoso GUI or bridge required. Parses maestro.sdb + active.state XML to extract output expressions, resolves the PSF directory from history.sdb, evaluates Ocean-style expressions (getData, dB20, phaseDeg, bandwidth, ymax, VF, VT…), and returns structured JSON results. Use this skill whenever: - The user asks "what is the gain / phase margin / bandwidth from the simulation?" - `maeGetOutputValue` returned nil (requires GUI results loaded in memory) - The user wants to check simulation results offline or from a script - The user wants to read PSF files / evaluate output expressions from a Maestro session - Any request involving Maestro output expressions, PSF files, or ADE results without GUI
Maestro (ADE Assembler) session management and simulation. Use when: running simulations via Maestro, configuring tests/analyses/outputs, updating design variables, reading results.
Evolve skills from vcli session history. Use when: (1) user says "根據歷史進化技能" / "evolve skills from history" / "覆盤技能", (2) after a debugging session to capture what went wrong, (3) periodic skill maintenance to close knowledge gaps revealed by real usage. Reads cmd.jsonl + per-session SKILL logs, finds failure/correction/gap signals, maps them to skills in .claude/skills/, and writes concrete improvements.
Execute SKILL code on Virtuoso. Use when running SKILL expressions, querying cellview data, listing libraries/cells, or interacting with Virtuoso programmatically.

Establish connection to Cadence Virtuoso via the virtuoso-cli bridge.
When user shows you the RAMIC Bridge banner like this:
┌─────────────────────────────────────────┐
│ vcli (Virtuoso CLI Bridge) — Ready │
├─────────────────────────────────────────┤
│ Session : 4e3898b12b7c-user-6 │
│ Port : 38669 │
│ SSH : 2222 │
│ Version : 0.3.2 │
│ Daemon : ~/.cargo/bin/virtuoso-daemon │
├─────────────────────────────────────────┤
│ Terminal: vcli skill exec 'version()' │
│ Sessions: vcli session list │
└─────────────────────────────────────────┘
Use these commands to connect:
# 1. Create SSH tunnel
ssh -f -N -L <Port>:127.0.0.1:<Port> -p <SSH> user@localhost
# 2. Test connection
VB_PORT=<Port> VB_SESSION=<Session> vcli skill exec '1+1'
Example from the banner above:
ssh -f -N -L 38669:127.0.0.1:38669 -p 2222 user@localhost
VB_PORT=38669 VB_SESSION=4e3898b12b7c-user-6 vcli skill exec '1+1'
Ensure Virtuoso is running with the bridge loaded in CIW:
load("/path/to/virtuoso-cli/resources/ramic_bridge.il")
Set environment and test:
export VB_REMOTE_HOST=localhost
virtuoso tunnel status --format json
virtuoso skill exec "1+1"
virtuoso init.env — set VB_REMOTE_HOST at minimumvirtuoso tunnel startvirtuoso tunnel status --format jsonRBPython points to a valid python3 binary (use full path like /usr/bin/python3)conn.shutdown() error in /tmp/RB.log; restart with RBDLog = t then RBStop() then RBStart() in CIWRBStopAll() in CIW, or change VB_PORT in .envVB_SESSION to specify which session to connect to
