  • Bug fixes

You can download Circuit Diagram 3.0 Alpha 1 now.


Circuit Diagram 2.1 Released

8th January 2014

This update includes bug fixes as well as the following new features:

Integrated Circuit Component

It's now much easier to use any type of integrated circuit in your diagrams without having to create a custom component. The new Integrated Circuit allows you to represent circuits with up to 12 pins, by choosing the number of inputs/outputs and pin labels.

Properties Editor Scrolling

You can now scroll down to see the full list of properties available to change in the properties editor, for components with many options.

Component Format Updates

The format for components now supports more complex conditional statements, including both and, or and not operators, using a more intuitive syntax. There is now also the option to sign components using X.509 certificates, allowing users to verify that the component has not been modified since it was created by the author.

Please visit the downloads page to download this version.


Circuit Diagram 2.0 Released

5th August 2013

This is the stable release of Circuit Diagram 2.0 - the improvements from 2.0 Beta 2 are mostly minor changes and bug fixes.

New in this release:

New website
New website

Today sees the launch of the newly designed website. As well as the redesign, we've added the new circuits page which allows you to share your circuit designs with other users of Circuit Diagram.

When you upload your circuit in Circuit Diagram's *.cddx format, a preview of your design will be automatically generated so that people can have a look at your circuit before they download it.

The forum has also been re-opened, so please share your comments and suggestions as they really do help decide the future direction of Circuit Diagram.

As ever, please upload any components you have made to the components page to help make Circuit Diagram better!

We hope to release the final version of Circuit Diagram 2.0 shortly, so check back soon.

This release includes a number of changes to make designing circuits easier, including automatic flipping of components when placing them and dragging from right to left or bottom to top. Documents can also be resized and there are many improvements to the use of keyboard shortcuts, including the ability to delete components by pressing the delete key on the keyboard.

Please see below for the full list of changes.

Windows Explorer Thumbnails

Thumbnails are now shown in Windows Explorer for Circuit Diagram Documents, as shown in the picture below. This feature has been difficult to get working, and there may be problems with the thumbnails not appearing - please leave a comment to let me know if they are working or not.

The following new features have been added since Circuit Diagram 2.0 Alpha 3:

  • Automatically flip components when placing
  • Delete components using keyboard delete key
  • Resize document
  • Document properties window
  • Print document
  • Recent files list
  • Confirm when exiting with unsaved changes
  • Thumbnail previews in Windows Explorer for CDDX files
  • Show shortcut keys in toolbox

Circuit Diagram 2.0 Alpha 3 Released

28th March 2012

This realease includes the following new features:

  • New components: microcontroller, demultiplexer and inductor
  • Flip & rotate components
  • Open XML files from previous versions of Circuit Diagram
  • Text formatting for components (including subscript and superscript)
  • CDDX updates
  • Other fixes

Important when upgrading from version 2.0 alpha 2:

  • Any compiled (*.cdcom) components you have downloaded separately must be re-downloaded
  • Unfortunately, it is not possible to open CDDX files created in 2.0 alpha 2 in this version, but all XML files from previous versions can be opened

If you wish to downgrade back to 2.0 alpha 2 after installing this version, you will need to uninstall the new version first.

If you have any problems please get in touch using either the forum or contact page.


Circuit Diagram 2.0 Alpha Released

25th January 2012

A preview of Circuit Diagram 2.0 is now available to download. Please note that it is still in the development stage, and you may encounter problems using it.

Design Your Own Components

A completely redesigned system for components, which will now be loaded at runtime rather than being hard-coded into the application. They will no longer be written in code, but in XML, making it easy for anyone to write their own components to use in their diagrams.

This will enable the following features:

A tutorial for making your own components is also available.

Editing

Select and move multiple components at once while editing.

Shortcuts and Toolbox

Asign keyboard shortcuts to components and customize the items in the toolbox.

Other Improvements

Also included are many other improvements, such as the proper rendering of connections on certain components. (You may have noticed that connections are not drawn properly for the inputs of components such as logic gates, and that three wires joining at the same point did not show as a connection.)

OPC-Based File Format

The new Circuit Diagram Document (*.cddx) file format brings with it the following improvements:

  • Stores connection information as well as layout information meaning that it
  • contains all the data needed to simulate a circuit (simulation is not supported by Circuit Diagram)
  • Open Packaging Conventions based - can be opened using a zip library and XML parser
  • Custom components used in the circuit can be embedded within the document

Note: the structure of this file format is still subject to change, and files could become incompatible with future versions until the format is finalised.

Download

Before downloading, please be aware of the following:

  • Some features from the stable version have not yet been implemented
  • If you create and save circuits using this version you may not be able to open them in a future version as the file format has not been finalised

Reporting issues:

Not all components from the previous version have been converted over yet.

A prerelease version can be downloaded here for testing.
