• matplotlib (for plotting)
• numpy (for numerical computation)

Usage

See the examples directory for various examples of using InSpice.

Basic example:

import InSpice
from InSpice.Unit import *

circuit = InSpice.Circuit('Simple RC Circuit')
circuit.R('1', 'input', 'output', 1@kΩ)
circuit.C('1', 'output', circuit.gnd, 1@µF)
