PCBSchemaGen Benchmarks
Two benchmark suites for LLM-driven PCB schematic synthesis, from the paper PCBSchemaGen: Reward-Guided LLM Code Synthesis for Printed Circuit Board (PCB) Schematic Design with Structured Verification.
Correctness in this domain is not defined by unit tests: there are no per-task golden references, and SPICE does not validate schematic-level correctness. Instead, each task is scored by a deterministic structural verifier against real-IC pin- and topology-level constraints (no LLM, no API key, no cached results). The verifier and knowledge graphs live in the GitHub repository.
Suites
| Config | Tasks | Easy / Medium / Hard | Real ICs | Domains |
|---|---|---|---|---|
pcbbench |
62 | 17 / 28 / 17 | 41 commercial | 22 |
open_schematics |
165 | 67 / 63 / 35 | 439 commercial | 22 |
| Total | 227 | — | 480 | 22 |
Load
from datasets import load_dataset
pcbbench = load_dataset("Hzou9/PCBSchemaGen-Benchmarks", "pcbbench", split="test")
ose = load_dataset("Hzou9/PCBSchemaGen-Benchmarks", "open_schematics", split="test")
print(pcbbench[0])
Fields
Both suites share these 10 core fields:
| Field | Description |
|---|---|
id |
Task identifier |
level |
Difficulty: Easy / Medium / Hard |
type |
Circuit type (e.g. Sensing, Power, Digital) |
task |
Natural-language design specification |
input_nodes |
Required input net(s) |
output_nodes |
Required output net(s) |
input_voltage |
Input voltage / range |
output_voltage |
Output voltage / range |
components |
Required component set (real ICs and/or passives) |
sub_module_name |
Canonical sub-module name for the target circuit |
open_schematics additionally carries two optional ground-truth fields, present on a subset
(20/165) of tasks and null elsewhere:
| Field | Description |
|---|---|
n_gt_components |
Ground-truth component count for the reference schematic |
gt_component_types |
Number of distinct ground-truth component types |
Evaluation
A candidate is a SKiDL (Python) schematic-generation program. Run it, then score the resulting
schematic with the deterministic 5-layer verifier in the GitHub repo (framework/topo/), which
checks pin-level assignments and topology against constraints induced from real IC datasheets.
See the repo README for the runner and per-task configuration.
