PCEval Dataset
PCEval: A Benchmark for Evaluating Physical Computing Capabilities of Large Language Models
This is the dataset accompanying the paper “PCEval: A Benchmark for Evaluating Physical Computing Capabilities of Large Language Models,” accepted at NeurIPS 2026.
Authors: Inpyo Song, Eunji Chon, Jangwon Lee
Affiliation: Intelligence and Interactive Systems Lab, Sungkyunkwan University
Overview
PCEval evaluates large language models on physical computing tasks, including logical circuit generation, physical breadboard layout generation, and code generation. Each project provides a natural language description, circuit diagrams, source code, and an automated test scenario.
Projects are organized into four complexity levels:
- Level 1: Single component behavior verification.
- Level 2: Handling changing input values.
- Level 3: Component state changes based on inputs.
- Level 4: Creative projects combining multiple components.

Usage
- Get the code:
git clone https://github.com/eunjichon/PCEval-Source.git cd PCEval-Source - Download the dataset and place the project files under
projects/, as shown above. - Set up the environment by following How to start. Install PlatformIO and the modified Wokwi CLI from the GitHub Releases, add the CLI to your
PATH, and set yourWOKWI_CLI_TOKEN. - Build and test a project:
cd projects/arduino/level1/led_blink_basic pio run wokwi-cli . --scenario scenario.yaml --diagram-file diagram.json # To test the physical breadboard layout: wokwi-cli . --scenario scenario.yaml --diagram-file diagram_breadboard.json
For evaluation scripts and experiment instructions, see the code repository and its source documentation.
