Very good news :) What do you intend to do with your Milkymist-ng SoC ported on this De0-Nano board? Is it just to provide a cheap demo-board for Milkymist-ng SoC? Or do you have some precise project? It's pretty cool to see the Milkymist (ng or not) SoC being ported to other FPGA and boards. It shows how good the design is and how easily you can cut it into pieces and just take what you want (and what can fit into smaller FPGA) to do whatever you like. Please keep sharing with us the wonderful things you achieve using and hacking Milkymist/Migen etc :) Cheers, -- Yann Sionneau _______________________________________________ http://lists.milkymist.org/listinfo.cgi/devel-milkymist.org IRC: #milkymist@Freenode
