Autorouting buses
The circuit shown below is used in this example. Bus 1 consists of the five
nets that connect the two ICs.
Note To autoroute buses, the topology for the nets, as set in the Net edit dialog box, must
be set to either Daisy chain or Star and the nets must be part of a Bus Group (in the
Groups tab of the Net edit dialog box). Refer to the Setting Group Parameters section of
Chapter 5, Working with Traces and Copper , for more information.
