Shortcuts:

Usage:

tool [name|info]

where name may be one of box, wiring, netlist, or pick.

Summary:

The tool command selects or queries the mode of operation of the mouse buttons in the layout window. Each tool type has a unique set of button bindings.

Without arguments, the tool command selects the next tool type in round-robin fashion. With a tool type as argument, the button bindings switch to those for the indicated tool. With the info option, a summary of the commands bound to each mouse button is given for the current tool.

The default mouse bindings for each of the three tools is as follows:

• Box Tool

  left

  Move the box so its lower-left corner is at cursor position

  right

  Resize box by moving upper-right corner to cursor position

  middle

  Paint box area with material underneath cursor

  In addition, you can move or resize the box by different corners by pressing left or right, holding it down, moving the cursor near a different corner and clicking the other (left or right) button down then up without releasing the initial button.
• Wiring Tool

  left

  Pick wire material and size from under the cursor and begin interactive wire placement.

  right

  Cancel interactive wire placement.

  middle

  Place a wire at the position shown by the interactive wire tool highlight box, and continue interactive wire placement.

  shift-left

  Change the type of wire to the next plane (e.g., metal1 to metal2)

  shift-right

  Change the type of wire to the previous plane (e.g., metal2 to metal1)

  shift-middle

  Place a contact at the current location and switch to the wire type on the next plane.

  scrollwheel up

  Increase the wire size by one unit

  scrollwheel down

  Note that the methods for the wire tool differ significantly between Tcl-based magic, with its interactive capabilities, and non-Tcl-based magic.
• Netlist Tool

  left

  Select the net containing the terminal nearest the cursor

  right

  Toggle the terminal nearest the cursor into/out of current net

  middle
