I'm... actually shock that somebody care about Xilinx.
I had to do Xilinx in my CE classes. It was terrible software, we joked that the CE and EE people code that software. Crashed all the time, made me so paranoid that to this day I would often ctrl+s every few minutes just in case my IDE crashes.
FWIW new Xilinx silicon is programmed by a new software suite, Vivado - which is much better than the terrible ISE you probably had to use in your class.
