xilinx Edititons

yes

Yes, but you may find that you have to muck about with environment variables such as XILINX, XILINX_EDK, and LMC_HOME when changing between which version you're running.

yes. to switch between them, edit the xilinx and xilinx_edk environment variables. i always have this setup because sometimes the new version breaks my compile. and sometimes the difference is subtle and i don't notice for months. nb: edk will only run with the ise of the same version.

And in a Linux environment this is trivial, you just source the appropriate settings.sh scripts for EDK and ISE. With consistently named installation dirs you can have as many versions as you like, and just script the selection process.

$ XIL_VER=9.2 source /etc/profile.d/xilinx_tools.sh
