Hi all,
I just completed building the tools (Yosys, arachne-pnr, and icebox) for the
Lattice ICE-40. It appears this will fit on a 4GB SD card.
With the board that XESS is making this will be a standalone HDL development
system with GTKWave, XSTOOLs, Iverilog, arachne-pnr(place and route), Yosys
(Yosys is a framework for Verilog RTL synthesis), icebox(this will not be
needed since XESS is going to push the bit file with GPIO instead of USB), and
MyHDL.These were built on a custom image for the Raspberry Pi 2 B with Yocto.
If you have any questions let me know.Regards,
Below are some tests that I ran on Raspberry Pi 2 B.
