An MCP server that brings QSpice circuit simulation to AI assistants, design schematics, run simulations, and analyze results through natural language. Built to help engineers, students, and makers explore electronics faster.
This repository also configures its own agents. See what HAbedini-qspice-mcp tells them →
Skill Claude CodeCodex
Diagnose a QSpice simulation that does not converge, stops early, or gives no usable waveform. Fix that simulation. Use this skill when a run has an error. Use this skill when the log shows "no convergence", "timestep too small", a singular matrix, or a gmin-stepping failure. Use this skill when V(out) is absent or…
Skill Claude CodeCodex
Operate the QSpice MCP server from the circuit through the waveform. Discover a circuit. Or author a circuit. Generate a netlist. Run a simulation. Read a waveform. Or measure a waveform. Use this skill at the start of any QSpice task. Use this skill when you are not sure which tool to call. Use this skill to simulate…
Skill Claude CodeCodex
Author a QSpice .DLL custom-device block for a mixed-signal C or C++ model. Scaffold that block. Build that block. Validate that block. Use this skill to add a controller or a behavioral block that compiled code supports. Use this skill to generate a C++ scaffold from a symbol. Use this skill to build the DLL. Use…
Skill Claude CodeCodex
Simulate a switching power converter in QSpice. Characterize that converter. Use this skill for buck, boost, or other SMPS work. Stage a transient analysis or an AC analysis. Measure efficiency and step response. Assess loop gain, phase margin, and gain margin for stability.
Skill Claude CodeCodex
Place schematic components on a readable grid with no overlap. Use suggestcomponentplacement, addcomponent with autoplace, or applyschematiclayoutspec for a batch JSON spec. Keep each part upright at 0° rotation. Follow the workflow coordinate tables for a complex circuit such as a buck converter.
Skill Claude CodeCodex
Inspect a QSpice waveform result after a simulation. Derive a waveform result. Measure a waveform result. Use this skill to read a signal from a .qraw file. Use this skill to compare nodes. Use this skill for a derived expression such as V(out)-V(in). Use this skill to measure RMS, peak, gain, or THD. Use this skill…
