Model Description

CircuitExpert-GPT is a language model finetuned for electronic circuit analysis, explanation, and simulation question answering.
It is especially skilled at parsing and interpreting LTspice netlists, analyzing schematic structures, and providing structured, step-by-step responses about circuit function, key components, calculations, and improvement suggestions.


Intended Use

  • Analyze, explain, and review analog/digital circuits from text-based descriptions or netlists (esp. LTspice).
  • Summarize circuit function, identify key components and their roles.
  • Perform basic engineering calculations (frequency, current, voltage, duty cycle, etc.).
  • Suggest possible improvements, safety or reliability upgrades.
  • Assist in design review, troubleshooting, and educational contexts.

Model Inputs

  • Circuit netlists (LTspice or similar)
  • Natural language questions about circuits, modifications, or troubleshooting

Model Outputs

  • Well-structured, industry-relevant answers in this format:
    • Circuit function
    • Key components & role
    • Basic calculations
    • Possible improvements

Training Data

  • Example and real LTspice netlists
  • Electronics engineering textbooks, public domain Q&A, expert annotations
  • Manually curated Q&A pairs on circuit design, modification, and analysis

Limitations

  • Not for high-voltage, medical, or safety-critical design without human review
  • Answers only as good as netlist/text input; no schematic image understanding
  • May not generalize to extremely novel or unconventional circuits
