EEBench Evaluates AI Circuit Design Capabilities Using Declarative Code
Key points
- OpenAI's GPT-6 Astra demo showed AI working on circuit boards in KiCad.
- EEBench uses declarative code (atopile) for AI circuit design evaluation.
- The benchmark tests AI on real-world challenges like capacitor tolerances.
- AI models demonstrate knowledge of electronics but struggle with practical application.
AI in Circuit Design
OpenAI recently demonstrated GPT-6 Astra working on a circuit board in KiCad, sparking interest in AI's capabilities in electronics design. This demonstration raises questions about how to effectively measure the quality of AI-generated electronic designs.
Limitations of Graphical Tools for AI
Current AI models possess extensive knowledge of electronics, having processed textbooks, datasheets, and code. However, when operating graphical CAD tools, AI agents spend considerable effort navigating the interface, focusing on coordinates, menus, and application states rather than core electronic design principles. This overhead can obscure their actual understanding of electronics.
EEBench's Declarative Approach
To address the limitations of graphical interfaces, EEBench utilizes atopile, a declarative code-based approach for circuit design. This method allows AI agents to work directly with components, connections, and electrical constraints. By operating on code, the AI can modify designs, build them, run simulations, and identify failures without leaving the project environment, leading to a more focused evaluation of its electronics expertise.
Real-World Design Challenges
EEBench incorporates real-world complexities into its tasks. For example, one task involves designing a circuit to maintain a processor's power supply for 20 ms after a 5V supply loss, ensuring the voltage stays above a 3.0V brownout threshold. While AI models intuitively suggest adding a capacitor, the benchmark accounts for practical factors like capacitor tolerance, voltage-dependent capacitance, cost, space, and recharge time. EEBench simulates power outages, measures voltage, effective capacitance, recovery, and checks against physical limits, providing a comprehensive assessment of design robustness.

Reporting from
EEBench, a new benchmark, assesses AI models' ability to design electronic circuits by having them work with declarative code rather than graphical CAD tools. This approach allows AI to directly manipulate components and electrical constraints, providing a more accurate measure of their electronics knowledge. The benchmark highlights that while AI models possess significant electronics knowledge, applying it effectively in real-world scenarios with component tolerances and physical constraints remains a challenge.
