CircuitFormer Dataset This dataset contains a collection of 33,889 analog circuit netlists, images, and metadata collected from 62 textbooks. Directory Structure The dataset is organized into the following flattened directories (no train/test subfolders): images/ : Circuit diagrams (PNG format). metadata/ : JSON files containing circuit descriptions, names, and source information. netlists/ : SPICE netlist files ( .cir ). Index Files The dataset uses JSONL (JSON Lines) index files to map entries to their respective files. Index File Count Description : : : index.jsonl 33,889 Master Index . Contains all 33,889 circuits in the dataset. Maps every ID to its image, netlist, and metadata files. sim error index.jsonl 2,548 Simulation Errors . A subset containing only circuits that failed prior simulation checks (based on IDs listed in simulation check/errors list.txt ). sim valid index.jsonl 31,341 Simulation Valid . The complement of the error index. Contains all 31,341 circuits that did NOT fail the simulation check. sim valid filtered index.jsonl 18,011 No X Filtered . A subset of sim valid index that excludes ONLY subcircuits ( X ). All other components (including J , T , etc.) are a…
