VHDL Notepad++ plugin

Once upon a time i wrote a VHDL plugin for the excellent Notepad++ Editor. With this plugin you can extract the signals out of a VHDL Entity declaration or create an Instantiation with this Entity. You can also instantiate the copied Entity in an template Testbench file. Check it out at: http://sourceforge.net/projects/nppvhdlplugin/
