virtuoso-bridge-lite

Run Cadence Spectre simulations remotely via virtuoso-bridge: upload netlists, execute, parse PSF results. TRIGGER when the user wants to run a SPICE/Spectre simulation from a netlist file, do transient/AC/PSS/pnoise analysis outside Virtuoso GUI, parse PSF waveform data, run multiple simulations in parallel across one or more servers, check simulation job status, or mentions Spectre APS/AXS modes. Also triggers for sim-jobs, sim-cancel, or parallel/concurrent simulation requests. Use this for standalone netlist-driven simulation — for GUI-based ADE Maestro simulation, use the virtuoso skill instead.

Bridge to remote Cadence Virtuoso via Python API. TRIGGER when user mentions: Virtuoso, Maestro, ADE, CIW, SKILL, layout, schematic, cellview, OCEAN, or any Cadence EDA operation.

Semantic cleanup and curation of Spectre/SPICE transistor netlists for analog review or reusable reference circuits. Use when Codex needs to understand generated ADE/PEX netlists, split DUT/testbench/run decks, optionally strip layout-derived MOS tail parameters by reasoning, rename random nodes/instances into semantic names, or prepare clean comparator/opamp/SAR reference netlists. Scripts in this skill are checkers only, not primary cleanup engines.

Black-box optimization of design parameters using TuRBO or scipy. TRIGGER when the user wants to optimize, tune, size, sweep, or explore a design space to meet specs. This includes circuit sizing (W/L, bias, passives), finding optimal operating points, minimizing power-delay or noise-power tradeoffs, or any task where multiple parameters need to be searched to hit a target. Also trigger when the user says things like 'find the best sizing', 'help me tune this', 'run an optimization', 'what values give me the best FOM', or 'sweep these parameters to meet spec'. Do NOT trigger for single-variable parametric sweeps or analytical calculations.
