 ### Install Xilinx Vivado

 Vivado can be installed in two ways: either through an "All OS installer Single-File Download", or via the "Linux Self Extracting Web Installer".
 Neither option is great:
 the "All OS installer" is a huge download of around 20 GB (and the Xilinx download servers seem to be overloaded regularly), but it supports an unattended installation.
