Bastion Circuit Designer

Draw a circuit, run it, and watch the current flow. Simulation, instruments, microcontrollers and an AI co-pilot in one desktop app.

  • Live simulation. The solver runs while you build, and the current flows along the wires.
  • Real SPICE too. ngspice is built in, and the two solvers can be compared on the same circuit.
  • Instruments. Oscilloscope, multimeter and an 8-channel logic analyzer.
  • Analysis. AC sweep with a Bode plot, Monte Carlo tolerance runs and a SPICE linter.
  • Microcontrollers. ESP32, RP2040 and STM32 with a serial monitor, an OLED, an LCD and a motion sensor.
  • Co-Pilot and MCP. An AI assistant in the app, and an MCP server so other tools can read and edit the circuit.
  • Parts and export. A bill of materials with prices, KiCad export and OpenSCAD enclosures.
  • Academy. Lessons about electricity and electronics.
