Xilinx has turned asshole against us, because their reseller misreported numbers. Our boss was fuming after the conference and told me to find another vendor.

We are now using Efinix chips and their forum and direct support is wonderful. I had discussions with their tool developers about UI design decisions that actually led to improvements. Imagine trying to get something like that done with Xilinx - they have grown too big to care unless you buy millions of chips.
