I am having a similar problem. Using busses to connect components on the same sheet seems to work fine. When I used busses between sheets the netlist generator reports "Bad Bus Label" for each bus. I have read section 5.5 and the process seems fairly clear but I haven't been able to make it work. Any ideas?
