ChunkSchematic is a simple, yet incredibly powerful and flexible schematic capture software package for Windows. At Chunk Systems we design effects pedals for bass guitar. For years we've been looking for a reliable and affordable schematic capture tool which gives us results in a useful netlist format. Eventually we gave up and wrote our own.
Anyone can download and use ChunkSchematic, but a license for the correct pin count is required to export a netlist. You can obtain licenses in two ways:
The idea behind this purchasing system is that ChunkSchematic can be useful for everybody from hobbyists and students through to professional engineers.
For more information about the goals and features of ChunkSchematic, see the manifesto below.
Download the current release of ChunkSchematic.
For the moment you just unzip the file to your hard drive and run ChunkSchematic.exe. An installer will be included with later versions. License and ReadMe files with more information are included inside the zip file. A basic help system is included to get you started. The latest libraries are also included.
By installing the software you agree to be governed by the license agreement.
You can purchase licenses for ChunkSchematic through Paypal by clicking one of the Buy Now buttons below. Prices are in Australian dollars but exclude Australian GST, which will be added for Australian customers. Orders will be processed and license keys sent to you by email on the next Australian business day. You can upgrade your capacity at any time by purchasing extra pins.
Please contact firstname.lastname@example.org with any questions on licenses or purchasing.
contributing to the libraries
When you design a new product there will sometimes be parts that you want to use that will not be in the libraries and you will need to add them. Chunk Systems wants you to contibute these additions and improvements to the wider Chunk Schematic community because it makes Chunk Schematic more useful. In exchange for your help in expanding the libraries, Chunk Systems will offer you more license capacity, which means that you are allowed to export larger netlists from Chunk Schematic.
The amount of capacity offered depends on how useful we think your addition is. However, we will generally follow a policy of giving you a 150% return on your work in terms of pins. That is, if you add a new part with 100 pins, we will offer to add 150 pins to your licensed capacity. You can reject our offer if you like, in which case your additions or modifications will not become part of the publically available library. However, our intention is to be generous. The idea is that people who make significant and regular contributions should be able to use Chunk Schematic for free.
To contribute, email your modified ckl files to email@example.com and include a description of your changes.

Here's a summary of what ChunkSchematic is all about.
simple interface, powerful backend
ChunkSchematic schematic and library files are written in a human-readable language called MOLLUSC, the Modular Objective Lightweight Language for Uncomplicated Schematic Capture. This means that, although it has a simple user interface, you can achieve virtually anything in Chunk Schematic by writing MOLLUSC code yourself. For example, MOLUSC lets you reuse and modify part of an existing component definition to create a new component.
easy to add new parts
Whereas most schematic capture packages require you to come to grips with a clunky component editing interface in which you need to place each pin by hand, ChunkSchematic lets you list the pins in a simple text format and let the system place them automatically. This dramatically reduces the time it takes to add large complex components with many pins.
If you've done a lot of schematic capture, you'll know that you spend a lot of your time tidying up wires after moving components around. Chunk Schematic reduces the need to rewire with its intelligent wire layout system. Also, most schematic capture packages define component labels in a fixed location relative to the body of a component, which can be rotated or flipped. This means that as you move components around you constantly need to be adjusting the position of these labels so they don't overlap other components. Chunk Schematic avoids this problem by including only those component body and label orientations that make sense for a given component. These orientations are easy to define using MOLLUSC. You'll spend less time cleaning up the details with Chunk Schematic.
Chunk Schematic exports netlists in the universally supported Protel format. You can use these netlists with virtually any PCB layout package including the freely available Protel Autotrax.
an interface that works
Chunk Schematic's zooming and scrolling engine has evolved over several years and is very solid. Unlike other packages, you won't see rendering glitches when you zoom or scroll. All the professional features you'd expect are there, including Cut, Copy, Paste, mousewheel support and multi-level Undo. Chunk Schematic's interface is simple and intuitive and uses the same selection and editing paradigms you're used to from other Windows software.
affordable and collaborative
Chunk recognises that the usefulness of a schematic capture packages is largely determined by the size of the library of components that exists for it. There are, therefore, two ways to get a license for Chunk Schematic. One way is to pay for it, the other is to contribute component definitions to the public library. Like many other schematic capture licensing schemes, a Chunk Schematic license enables you to create designs up to a certain number of pins and Chunk will reward each useful contribution to the library by increasing the number of pins for which you are licensed. This means that Chunk Schematic is affordable for everyone from the hobbiest through to the professional engineer.
