typeCAD Graphviz

View connections in your typeCAD project.

Getting Started

Prerequisites

• a working typeCAD project
• Graphviz Interactive Preview

Installation

Run the following command in your project directory, where your typeCAD package.json file is located:

npm i @typecad/graphviz

Usage

import { PCB, Schematic } from '@typecad/typecad';
import { graphviz } from '@typecad/graphviz';

let typecad = new Schematic('project');

typecad.create();
graphviz(typecad.Schematic);

Options

Themes

There are 3 themes available:

• light
• dark
• nord

graphviz(typecad.Schematic, { theme: 'nord' });

Ignored Prefixes

By default, components with the following reference designator prefixes are ignored: 'R', 'C', 'L', 'D', 'SW', 'SJ'. This default behavior leaves just the major components, this can be changed:

graphviz(typecad.Schematic, { theme: 'light', ignoredPrefixes: new Set(['SW', 'SJ']) });

All Connections

By default, only connections that are named (typecad.named('en').net(...);) are graphed. This behavior can be changed:

graphviz(typecad.Schematic, {theme: 'dark', ignoredPrefixes: new Set(['SW', 'SJ']), ignoreNetNames: false });

View

Open the project_net_connectivity.dot file. Ensure the plugin linked above is installed and use that to view the graph.

In the graph preview window, there are some options, choosing Bidirectional will show the most applicable information when clicking on the graph components. Visually, Dot and FDP are probably the most useful.
