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

Is #IceStorm 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:

element14.com/community/thread

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.

@h

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So, whilst the tooling is not really open source (to my knowledge, which may be outdated), some people find it very useful to make open source things.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

@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.

@vertigo @cstanhope @jjg

@h

Word.

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 :) )

@jjg @h @cstanhope @vertigo Let me see but this tool IceStorm will improve GPU acceleration in someway or what improvements would be in graphics acceleration ?. Just curious I don't know so much ..... 🤔

@neomoevius fpga has many applications, my interest is in producing application-specific logic and experimental cpu architectures.
