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.
