This blog doesn't seem to talk about the OSS toolchain, litex/vexriscv are very neat but they don't replace Vivado, right?
Like all open-source, it's an ongoing effort. Bunnie has a comparison, https://www.bunniestudios.com/blog/2017/litex-vs-vivado-firs...
> Thanks to the extensive work of the MiSoC and LiteX crowd, there’s already IP cores for DRAM, PCI express, ethernet, video, a softcore CPU (your choice of or1k or lm32) and more.. LiteX produces a design that uses about 20% of an XC7A50 FPGA with a runtime of about 10 minutes, whereas Vivado produces a design that consumes 85% of the same FPGA with a runtime of about 30-45 minutes.. LiteX, in its current state, is probably best suited for people trained to write software who want to design hardware, rather than for people classically trained in circuit design who want a tool upgrade.
I think transpute likely meant to link F4PGA[1] or one of the projects it makes use of (Yosys, nextpnr, Project IceStorm, Project X-Ray, etc).
Thanks for the pointer! DARPA ERI investment was initially directed to US academic teams, while Yosys & related decentralized OSS efforts were barely running on conviction fumes in the OSS wilderness. Glad to see this umbrella ecosystem structure from LF Chips Alliance. Next we need a cultural step change in commercial EDA tools.
