The w11 project uses the open source VHDL simulator

  ghdl

It used to be part of most distributions. Unfortunately the Debian maintainer

for ghdl refused at some point to integrate ghdl into Debian Etch. Therefore

ghdl was part of Debian Lenny, and again of Debian Squeeze, and is missing

again in Debian Wheezy (the current 'stable').

The glitch at Debian unfortunately lead to the removal of ghdl from Ubuntu,

which is based on Debian. Ubuntu Lucid (10.04) and up to Oneiric (11.10)

included ghdl, the currently maintained versions Precise (12.04 LTS) and

alter don't.

To install ghdl on an up-to-date Debian or Ubuntu systems you have the

following options {as of early October 2013}:

- Ubuntu Precise, Quantal, and Raring

  Thanks to Peter Gavin Ubuntu packages for GHDL are available from his PPA

  'Personal Package Archives', see

    https://launchpad.net/~pgavin/+archive/ghdl

  So to install ghdl under Ubuntu use

    sudo add-apt-repository ppa:pgavin/ghdl

    sudo apt-get update

    sudo apt-get install ghdl

- Debian Wheezy

  Thanks to Joris van Rantwijk Debian packages for GHDL are available

  from the web site

    http://jorisvr.nl/ghdl_debian.html

  There are also Ubuntu packages, but Joris focus is clearly on Debian.

Only Debian and Ubuntu are actively used by the w11a developer. The

situation for other linux distributions is therefore just taken from

the respective web sites:

- Suse

  For Suse 12.2 and 12.3 un-official ghdl packages are available, but they

  seem to be based on the long obsolete ghdl version 0.27.

- Redhat/Fedora

  For Fedora 18,19, and 20 packages are available based on ghdl 0.29

- Gentoo

  Packages, marked 'unstable', are available based on ghdl 0.29 and 0.27
