VHDL Text Editor
Despite the multitude of text editors out there suitable for writing VHDL code, we would like to recommend the simple yet powerful gedit with its code snippet plugin.
If you are using a Linux-centric machine you can easily install gedit and its blugins with the command:
sudo apt-get install gedit gedit-plugins
If you want to see how gedit and ghdl go together for some VHDL development, please have a look at some tutorials.
