So, after looking over the design and PCB and BOM of the ASIC, it seems that all that's needed to build a clone of Avalon s units is the FPGA firmware?  everything else seems to be online that's needed to the plans off to a PCB factory and get populated boards back.   I doubt at an individual level the costs of building a clone would be worth it, but if someone was building a large miner why wouldn't this be a better route to go then redesigning a whole new system
