I have to write an essay for university and would really like to do this with latex. My document should have a graphic in which my data path is shown. Drawing a bus, ALU's and so on are absolutely necessary! Does anyone know if this is possible with circuitikz? In the examples I found some things regarding digital circuits but they never use ALU's and/or busses.
Or is there a better way to realize this?
Btw: I use texlive-full at Ubuntu 12.04 if this is important

Thanks in advance!
