SVG Schematic

Author:Ken Kundert
Version:1.1.0
Released:2020-08-18

This package allows you to create simple SVG schematics and block diagrams without a mouse. Instead, you build the schematic using Python to instantiate and place the symbols and wires.

Simple Example

Here is a simple example that demonstrates the package. It generates the schematic of a shunt RLC circuit:

from svg_schematic import Schematic, Resistor, Capacitor, Inductor, Wire
from inform import Error, error, os_error

try:
    with Schematic(filename='rlc.svg'):
        r = Resistor(name='R', orient='v')
        c = Capacitor(W=r.E, name='C', orient='v')
        l = Inductor(W=c.E, name='L', orient='v|')
        Wire([r.p, l.p])
        Wire([r.n, l.n])
except Error as e:
    e.report()
except OSError as e:
    error(os_error(e))

When run, it produces the following schematic:

_images/rlc.svg

Installation

Requires Python3. Works best with Python3.6 or newer.

You can download and install the latest stable version of the code from PyPI using:

pip3 install --user svg_schematic

You can find the latest development version of the source code on Github.

Contributions in the form of pull requests are welcome.

I tend to create symbols as I need them. If you create missing symbols, please consider contributing them back to the project.
