Xilinx’s tools seems to always come with their fair share of problems. I installed the latest version, Xilinx Vivado 2016.4, hoping that I could avoid hacky fixes to get it running (and playing nice with Windows 10, too!) I was wrong. (Turns out that this is normal, just look at the sample projects in “Zynq SoC Training” from EmbeddedCentric.com!) Current grievances: Bad workflow when developing a custom IP. Plenty of “Vivado Internal Exception” messages popping up every now and then.
