reda-spice

Simulate Electronic Circuit using Rust and the Ngspice Simulators.

Aim to replace PySpice :)

Features

Simulate

• .sp file parse

• NgSpice dynamtic library simulator

• NgSpice server simulator

• Execute op, dc and tran analysis

• Analysis draw

• Spice library

• .param and .option

Examples

let mut circuit = Circuit::new("Transient sin");

circuit.add_sine_voltage("input", "in", "0", SineVoltage::sin(u!(1 V), u!(100 Hz)));
circuit.add_resistor("1", "in", "1", u!(3 kΩ));
circuit.add_resistor("2", "1", "0", u!(1 kΩ));

let simulate = NgSpiceShared::default()?;
let mut simulator = circuit.simulator(simulate);
let command = TranCommandBuilder::default()
    .t_stop(u!(0.02 s))
    .t_step(u!(1 us))
    .build().unwrap();
let analysis = simulator.run_tran(&command)?;

analysis.draw_nodes(&Drawer::default(), &["in"], "./images/transient-sin-nodes.png")?;
analysis.draw_all_branchs(&Drawer::default(), "./images/transient-sin-branchs.png")?;
