2.In the Names field, type the names you want to create; for example,addr<0:3> or addr1 addr2 addr3.

3.Set the following options as needed:

If you want bus expansion of multiple wire names, turn the Bus Expansion field to on.

This option places multibit bus names as multiple names, one for each bit of the bus range, instead of one name. For example, for the name A<0:1>, the label A<0> is placed first, thenA<1>.

If you want to place multiple wire names, set the Placement field tomultiple.

This option lets you place wire names as if in single mode but prompts you to bring the rubberbanding line across remaining wires to be named.

4.Move the pointer to the desired location and click once.

If you place the wire name at a greater distance from the wire than the default, point on the wire that the label names.

5.Place the remaining names by moving the pointer above each wire to be named and clicking once to place the remaining wire names.
