@jjg The two biggest providers are Xilinx (with 51% of the market) and Altera. Xilinx appears to has made a killing with their focus on the ARM ecosystem. Intel bought Altera a couple of years ago, for $16 billion, so they're the second largest or the largest FPGA manufacturer, depending how you look at it. The circle is getting narrower. If you're aiming to support ARM due to their energy efficiency for example, Xilinx is a better way to go.
@jjg Xilinx offers a proprietary system that is based on FOSS, including a development environment and a system that facilitates code reuse (greatly helped by the ubiquity of Android on ARM).
So, whilst the tooling is not really open source (to my knowledge, which may be outdated), some people find it very useful to make open source things.
I haven't looked into Intel stuff, but it's well documented for what I see
@neomoevius I have no idea if Intel are playing nice with open source FPGA. They may well be, as they are being very decent on the GPU front, and they're playing catch up with ARM on a few fronts. But as you obviously know, Intel or any corporation their size is a cause for concern given what we see in the news.
My 5 minutes worth of research indicates that #icestorm has the capability of providing an open-source toolkit (now I just need to figure out if what I want to do will fit within the #fpga it supports :) )
