Electric plug-ins are additional pieces of code that can be downloaded separately to enhance the system's functionality. Currently, these plug-ins are available:

- IRSIM The IRSIM simulator is a gate-level simulator from Stanford University. Although originally written in C, it was translated to Java so that it could plug into Electric. The Electric version is available from Static Free Software at www.staticfreesoft.com/electricIRSIM-8.09.jar.
- Bean Shell The Bean Shell is used to do parameter evaluation in Electric. Advanced operations that make use of cell parameters will need this plug-in. The Bean Shell is available from www.beanshell.org.
- 3D The 3D facility lets you view an integrated circuit in three-dimensions. It requires the Java3D package, which is available from the Java Community Site, www.j3d.org. This is not a plugin, but rather an enhancement to your Java installation.
- 3D Axis Controller Once the 3D facility is installed, there is one extra part that can be added to enhance the display: a 3D axis controller. The 3D axis controller is available from Static Free Software at www.staticfreesoft.com/electricJava3D-8.09.jar
- Animation Another extra that can be added to the 3D facility is 3D animation. This requires the Java Media Framework (JMF) and extra animation code. The Java Media Framework is available from Sun Microsystems at java.sun.com/products/java-media/jmf (this is not a plugin: it is an enhancement to your Java installation). The animation code is available from Static Free Software at www.staticfreesoft.com/electricJMF-8.09.jar.
- Russian User's Manual An earlier version of the user's manual (8.02) has been translated into Russian. This manual is available from Static Free Software at www.staticfreesoft.com/electricRussianManual-8.09.jar.

To attach a plugin, it must be in the CLASSPATH. The simplest way to do that is to invoked Electric from the command line, and specify the classpath. For example, to add the beanshell (a file named "bsh-2.0b1.jar"), type:

`java -classpath electric.jar:bsh-2.0b1.jar com.sun.electric.Launcher`

On Windows, you must use the ";" to separate jar files, and you might also have to quote the collection since ";" separates commands:

`java -classpath "electric.jar;bsh-2.0b1.jar" com.sun.electric.Launcher`

Note that you must explicitly mention the main Electric class (com.sun.electric.Launcher) when using plug-ins since all of the jar files are grouped together as the "classpath".
