So what's state-of-the-art in open-source ?

Is where it's at? I'm interested in synthesizing cpu cores which I think puts me in the area of large-ish fabric devices but again I stopped looking for a few months and now I feel like I have no idea what to expect :)

@jjg @vertigo @h @cstanhope Hi again, at the moment I don't know so much about IceStorm, what is it about ? 🤔

@neomoevius open-source toolchain for FPGA:

Last I checked it was the only thing like it, but it was also targeting a specific device and I'm not sure if that's changed since the last time I did a deep dive.

@vertigo @h @cstanhope

@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.

As I understand it, neither of them offer an open-source toolchain, correct?

@neomoevius @vertigo @cstanhope

@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So, whilst the tooling is not really open source (to my knowledge, which may be outdated), some people find it very useful to make open source things.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
