Hi, Just received my Papilio Duo and LogiStart Shield. I went for the Duo as its not much more than the Pro. I'm not interested in Arduino, but rather VHDL design. I'm a complete beginner to electronics although I have quite a bit of experience of low level CPU programming. Looking to play around with basic boolean logic, output to the LogicStart shield to gain some experience with circuit design, then long term I want to start designing my own simple CPU. I'm confused as to where DesignLab comes in, it seems to be skewed towards Arduino development using ZPUino with the advantage that you can draw your own circuits? If I want to work on just the FPGA on the Duo is it best to stick with WebPack ISE, or does DesignLab have any advantages? Does WebPack ISE have a circuit viewer/editor? Thanks, Dean
