spicebridge

Overview

SPICEBridge is a specialized MCP server that bridges natural language processing with electronic circuit simulation. It provides 28 comprehensive tools covering the entire circuit design workflow, from template loading and component calculation to simulation, measurement, and spec verification. The server supports AC sweep, transient analysis, and DC operating point simulations, along with Monte Carlo and worst-case analysis capabilities. Beyond simulation, it offers features like KiCad export, schematic generation, and a cloud setup wizard for easy deployment.
