Hi, thanks for testing this!
> In order for icestorm to build, I had to add libusb to its inputs. I posted a patch "gnu: Move libusb from inputs to propagated-inputs" back in August which would fix that (by fixing libftdi). Adding libusb here is not the right fix. > The toolchain was tested with an fpga. It's producing the bitstream, and > iceprog works as well. Iverilog is performing simulation as it should. Nice :) > It would be helpful if we (I?) package gtkwave as well, so that one can view > the waveforms > from the verilog simulations. Yeah...
