|
| ## 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**. |

|
|
| ## 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. |
|
|
| ## Project Structure |
|
|
| Place the downloaded project files in the code repository's `projects/` directory: |

|
| ## Usage |
|
|
| 1. **Get the code**: |
| ```bash |
| git clone https://github.com/eunjichon/PCEval-Source.git |
| cd PCEval-Source |
| ``` |
| 2. **Download the dataset** and place the project files under `projects/`, as shown above. |
| 3. **Set up the environment** by following [How to start](https://github.com/eunjichon/PCEval-Source#how-to-start). Install PlatformIO and the modified Wokwi CLI from the [GitHub Releases](https://github.com/eunjichon/PCEval-Source/releases), add the CLI to your `PATH`, and set your `WOKWI_CLI_TOKEN`. |
| 4. **Build and test a project**: |
| ```bash |
| 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 |
| ``` |
|
