Drawing a Wire
„ To actually start drawing the wire, point the mouse to the location where you want
the wire to start and press Button-1 (or Shift-Button-1 to match the width of the layer
under the cursor).
You can then move the mouse to create the wire, which will follow the mouse
movements.
„ To create a vertex (bend in the wire) press Button-1 again. Notice that the vertex
slides along the previous wire segment so that you can move the mouse in any direction
and the wire will follow.
„ To prevent the vertex from sliding, press the a key, or select anchor vertex from
the pop-up menu that appears when you press mouse Button-2 (see Figure 92).
„ To end the wire, press Button-3 over an existing metal or poly of the same type as the
wire. You can also end the wire at any time with Button-3 not over current wire layer,
which allows you to exit wiring mode without completing a connection.
When you end the wire by completing a connection, the wire tool automatically snaps
the final wire segment to make the wire align properly with the existing rectangle.
„ To prevent this, end the wire by using Ctrl-Button-3 at the wire end-point.
Once a wire has been started, the Wire Menu updates its selections, as shown in Figure 92.
Figure 92: Wire Pop-up Menu After Wire Has Been Started
„ To change layers, drop a via using either the d or Shift-d hot keys, or use the popup menu on mouse Button-2.
„ To undo a wire segment or via, use the u hot key, or select undo from the pop-up
menu on mouse Button-2.
Example: If you are wiring in Met1 horizontally and drop a via, down (hotkey: Shift-d),
the via down to poly still moves in the horizontal direction (see Figure 93). In this case, you
are wiring the two left gates.
