Math & Science ⇒ Package for Digital Systems Block Diagrams

Is there something like that around?

I'm looking specifically for something that allows to draw black boxes (modules) with inputs/outputs, number of bits for each one of them, connection with other black boxes, number of bits that flow from one to another, etc.

Thank you.

I would suggest either pgf/tikZ or PSTricks.
