Ptolemy II 3.0.2 Release

Note:
This is not the most recent version of Ptolemy II. The most recent version can be found at http://ptolemy.eecs.berkeley.edu/ptolemyII/ptIIlatest/.

In Ptolemy II 3.0.2 the expression language has been reworked and the code generator u pdated. It also includes a set of mature and experimental domains, and a more comprehensive actor library than previous releases.

Quick Start Instructions

Ptolemy II is available in several formats:

Applets: You can browse Ptolemy II and run demonstration applets without downloading the distribution by accessing the web copy.
The web copy is merely a set of web pages that were created when we untar'd the distribution on the Ptolemy web site.
To access Ptolemy II via the applets, you can either go directly to the web copy, or go to the Ptolemy II 3.0.2 Applets page for more information.
Web Start: Web Start is a tool from Sun that makes installation and updates particularly simple.
The Web Start installation works best with Windows, but has also been tried under Solaris, Linux and Mac OSX (!).
The Web Start installation does not include source, but behaves almost exactly like a standalone installation: you can save models locally, and you need not be connected to the net after the initial installation.
Note that the Applet web copy and the Web Start installations are different, the web copy is a set of web pages where some of the pages contain applets, and Web Start is a set of jar files that get downloaded to your machine so that you can run Ptolemy II at a later time, even if you are not connected to the network. For details, see the Installation Summary
To download using Web Start, see the Ptolemy II 3.0.2 Web Start page.
Windows Installer: To download a Windows Installer, see the Ptolemy II 3.0.2 Windows Installer page.
Source: You can download either precompiled sources or the smaller source only distribution and install Ptolemy II, start vergil from the command line and follow the quick tour.
The source distribution has been compiled and run under Windows, Solaris and Linux.
If you intend to develop your own actors in Java, then you should download the source distribution.
To download source, see the Ptolemy II 3.0.2 Source Download page and then follow the installation instructions.
