I was surprised to find out, that in order to being able to contact Xilinx’s support, one must not only have a Xilinx account, but also have applied with that account for being able to write to Xilinx support. So, in essence, you can only ask Xilinx questions, if Xilinx grants you the right to ask them 😉 What kind of nonsense is that?
This fact alone is reason enough for me, not to buy their products. Not being able to write them straight away in case there is a problem and risking to not get any support in the end is simply not acceptable.
Praised be Lattice, where everybody can get all the support one needs! 🙂
