You can install the Sigasi 2.x Eclipse VHDL plugin through the Eclipse Market Place, as of Eclipse 3.6.

[Eclipse Indigo (3.7) users can use a shortcut: just drag this link into your running Eclipse to start the installation.]

Prerequisites: Eclipse

• You need to have at least Eclipse version 3.6, nicknamed Helios. If you have Eclipse 3.5 (or if your Helios version does not have the Eclipse Marketplace Client enabled) you should follow a different installation procedure.

• If you don't have Eclipse installed yet, the C/C++ flavor would be good place to start. Just download (Windows 64 bit / Linux 64 bit / Other versions), unzip and start.
• We recommend you also increase the heap size for Eclipse.

Note that we do not support Eclipse 3.5 (Gallileo) any more. (see system requirements)
