Circuit Simulation Analysis

Problem Addressed

Circuit review often turns natural-language specs, SPICE netlists, or schematic screenshots into reproducible simulation evidence. Manual modeling, simulation, plotting, and report writing can fragment across tools, while different circuits need different analysis mixes. This skill organizes that workflow: parse the input, select the right simulations, and produce charts plus a Word report.

How It Works and Where It Fits

The pipeline covers circuit parsing, simulation planning, simulation execution, and optimization analysis:
- Inputs include natural language, .cir / .sp / .net / .asc netlists, and OCR-recognized circuit images;
- Amplifiers, filters, oscillators, comparators, and bandgap references are mapped to DC, AC, .tran, .noise, .four, temperature sweeps, and related analyses;
- ngspice computes operating points, frequency response, transients, noise, and harmonics, while schemdraw renders the schematic and python-docx builds the Word report;
- The report contains the schematic, netlist, simulation setup, waveforms, theory-versus-simulation comparisons, and optimization notes.
Scope: it is suited to circuit simulation, performance verification, troubleshooting, and optimization suggestions. It is not intended for PCB layout/routing, FEM electromagnetic simulation, thermal simulation, or sensor-circuit design.
