Leveraging Claude Code for Hardware Development with SPICE and Oscilloscopes

In my recent experiments with Claude Code for hardware development, I explored its potential to create circuits from natural language prompts. While it handles simple designs well, complex circuits pose challenges in plain English. To enhance its capabilities, I integrated Claude with my oscilloscope and a SPICE simulator, significantly improving the validation of SPICE circuits, embedded programming, and data analysis tasks. This setup streamlines processes like normalizing time axes and aligning data, which were previously tedious.

I demonstrated this approach with a simple circuit and microcontroller, emphasizing that the method scales to more complex projects. Key insights include ensuring Claude doesn't guess physical setups, keeping measurement data fresh, and managing data through files rather than raw dumps. For microcontrollers, providing explicit pinout maps and a Makefile for essential functions like build and flash is crucial, allowing Claude to operate more effectively.

The demo setup includes specific repositories: 'lecroy-mcp' for LeCroy oscilloscopes, 'spicelib-mcp' for SPICE library integration, and 'rc-filter-demo-files' showcasing the workflow. This approach not only simplifies circuit design but also enhances the efficiency and accuracy of hardware development.
