It is possible to download and use the Xilinx tools for free. My company sells bare metal access to FPGA's and our customers do it all the time.

I agree with the tooling being a nightmare though. It is a 80gb+ install that fails half the time.

You forgot that it crashes in random times and that the text editor refuses to open files because sigasi can't be initialized

I didn't forget, I just didn't get past the install. ;-)

I admit I'm mostly familiar with the Intel (formerly Altera) side. There are no restrictions at all on the Xilinx side? That's pretty neat.

You sign up on their website and click ok on the long eula nobody reads and then click download. So yea, there are probably restrictions, but they don't have a paywall in front of them. This isn't legal advice at all.
