EVA is developped as an open source project. The major part of the source code is designed with the NanoScheme Language and requires no compiler nor specific developement tools. However, we encourage the use of a text editor with Lips editing capabilities such as Notepad++. For more information or to download this editor:

The EVA's core technology is designed using the Java language. The current implementation uses the SDK 1.4.2_02 version. You can have more information and download this software developement kit at:
