This article evaluates the proficiency of 11 contemporary Large Language Models (LLMs) in performing electronic circuit analysis.

Utilizing OpenCode, an open-source agentic framework, the LLMs are tasked with analyzing a clock generator’s resistor-capacitor (RC) network defined in a KiCad 9.0 schematic. To facilitate LLMs’ comprehension, an efficient preprocessing methodology is introduced to convert schematic data into structured CSV formats. The evaluation requires the models to parse circuit netlists, retrieve specifications from component datasheets available in the workspace, and calculate the critical circuit parameters, specifically the common-mode voltage and differential swing of the clock output.
