Editing Installing Xilinx ISE (section)

== Step 4: Adding the License Files and Creating an ISE Shortcut ==

In .envrc (you would pick the particular file for your login shell, for example, .bashrc for the Bash shell, which comes preinstalled on most Linux distros, or whatever shell you have set, .zshrc for zsh), add the following environment variable before running ISE to install the license: set "XILINXD_LICENSE_FILE" to "2100@ise.csse.rose-hulman.edu". In other words, you want to add the following line: <code>export XILINXD_LICENSE_FILE="2100@ise.csse.rose-hulman.edu" </code> at the bottom of .bashrc or similar (this syntax is a little bit different if you're using zsh). If you want to add more lines to the end of your .bashrc (.envrc) file, add a semicolon after the end of the line to make sure there are no issues with tabs/newlines.  (Sources: https://www.rose-hulman.edu/Class/csse/csse232/Lab0%20Course%20tools/, section 1; https://askubuntu.com/questions/58814/how-do-i-add-environment-variables#58828)

This means that you have to be on the campus network to access the Xilinx license server on Linux (to use Rose-Hulman's license). You can do this by connecting to the eduroam network on campus or by connecting to the [[Accessing the Off-Campus VPN|GlobalProtect VPN]] when off campus.

You might want to also add the following line to make it easier to run Xilinx commands without having to type the command every time in the terminal.
In .bashrc (or similar), after the "XILINXD_LICENSE_FILE" line, add (for 64 bit systems, use 64, for 32 bit, use 32, etc.):
<code>source /opt/Xilinx/14.7/ISE_DS/settings64.sh</code> (NOTE the capital X in Xilinx!) (you may want to include semicolon if you want to include more lines afterwards.)

Now restart your terminal. If you get an error like "settings64.sh not found" when starting a terminal session, you may have typed in the wrong filename.

To run ISE, type "ise" in the terminal (root user not required to run ISE). If you have an alias you want to bind that is called "ise" or similar in your .bashrc, just comment out that line using # before source.
