First, read and agree to the license, then click the button below to download and run the Hades editor via the Java Webstart launcher.

(hades-signed.jar) via Java Webstart; requires JDK 1.4.2 or higher.

Notes about Java Webstart

The Java Webstart launcher is a very convenient way to install, and run Java applications - literally at a click of a button. The integrity of the software is automatically checked by calculating digital signatures of the software files and comparing them to the reference values stored in the jar archive. However, due to the very high costs of commercial certificates, we have to use a self-signed certificate for the hades-signed.jar class archive file(s).

To actually run the editor after download, you have to ignore the warning about self-signed certificates being insecure. If you don't trust this, you can download the Hades software archive manually from our download page. However, this incurs an even higher risk than using Webstart, because the software integrity is not checked at all.

You can configure the behaviour of the Webstart launcher via the Java Webstart control panel. For example, you can disable the automatic download of new software versions via the control panel, if your internet connection is slow. On Windows, the Webstart launcher can optionally also create start-menu entries and desktop icons for Hades; just agree to this when prompted by Webstart.

What's next?

Please agree to start the Hades software when prompted by the Webstart launcher. This will open the Hades editor, and you can now use the popup-menu and component browser to add simulation components and wires to your schematic. Use the simulation control panel to start, pause, and stop the simulator; use glow-mode and the layers menu to customize the appearance.

To access the built-in examples, open the help menu, select demos, and then select one of the example circuits. The examples include a few simple circuits meant to demonstrate the basic functions of the simulator and user-interface, and a few demos typically used for courses on basic digital system design. Please check our download page and the website applet collection for other example circuits.

If you allowed Java webstart to create a desktop icon or start-menu entries, you can start Hades later via clicking those. Otherwise, just visit this web page again and click the button above to start Hades. Of course, the Webstart launcher will not download the software again (unless you deleted Hades from your Webstart cache, or an updated version of Hades is available). Finally, you can also start Hades via the Java Webstart configuration tool.

Please note that the Webstart launcher is configured to always start the Hades schematics editor as the main application. If you want to run one of the several smaller applications included in the Hades class archive file, you can use the Java webstart control application to create the required setup information (the name of the main class, e.g. hades.models.pic.PicAssembler, and parameters). Please check your Java virtual machine documentation for details about how to use the webstart configuration tool.

However, if you plan to integrate Hades into your own software environment (e.g. Eclipse), it might be better to simply download the Hades class archive (hades.jar) again from our download page. Please check the Hades tutorial for details about the required and/or recommended CLASSPATH settings etc.
