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 allowed.

Component Filtering Details (sim_valid_filtered_index.jsonl)

This index restricts netlists to only use the following Allowed Elements:

Initial	Component Type
C	Capacitor
D	Diode
E	Voltage-controlled voltage source (VCVS)
F	Current-controlled current source (CCCS)
G	Voltage-controlled current source (VCCS)
H	Current-controlled voltage source (CCVS)
I	Current source
K	Coupled (Mutual) Inductors
L	Inductor
M	MOSFET
Q	BJT
R	Resistor
S	Switch (voltage-controlled)
V	Voltage source
W	Switch (current-controlled)

Excluded Elements:

• A (XSPICE code model), B (Behavioral source)
• J (JFET), N (Verilog-A), Z (MESFET)
• O, P, T, U, Y (Transmission lines & XSPICE blocks)
• X (Subcircuits) - Commonly excluded to ensure raw component parsability.
