TITLE: Graph theory and computer chip design reference
QUESTION [6 upvotes]: Wikipedia says graph theory is used in computer chip design. 

... travel, biology, computer chip design, and many other fields. ...

Is there a good reference for that? I can imagine optimal way to draw cpu to chip is to draw shortest hamiltonian cycle in it.
