Key macro space implements the command tool.
Key macro shift-space implements the command tool box.
where name may be one of box, wiring, netlist, or pick.
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
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.
- Move the box so its lower-left corner is at cursor position
- Resize box by moving upper-right corner to cursor position
- Paint box area with material underneath cursor
- Wiring Tool
Note that the methods for the wire tool differ significantly between Tcl-based magic, with its interactive capabilities, and non-Tcl-based magic.
- Pick wire material and size from under the cursor and begin interactive wire placement.
- Cancel interactive wire placement.
- Place a wire at the position shown by the interactive wire tool highlight box, and continue interactive wire placement.
- Change the type of wire to the next plane (e.g., metal1 to metal2)
- Change the type of wire to the previous plane (e.g., metal2 to metal1)
- 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
- Decrease the wire size by one unit
- Netlist Tool
- Select the net containing the terminal nearest the cursor
- Toggle the terminal nearest the cursor into/out of current net
- Join current net and net containing terminal nearest the cursor
- Pick Tool
The pick tool is an interactive feature only available in the Tcl-based version of magic.
- Remove the current selection from the layout, place it in the pick buffer, and follow the cursor.
- Cancel the current pick buffer and stop following the cursor.
- Place a copy of the pick buffer at the current location, and continue following the cursor.
- Make a copy of the current selection from the layout, place it in the pick buffer, and follow the cursor.
tool is implemented as a Tcl script in the Tcl-based version of magic. The command duplicates the function of the original tool command, which remains for the non-Tcl based version of magic, and which performs the function of changing the cursor style in the window.
Button functions for each "tool" may be added to or modified in the startup scripts. The Tcl variable Opts(tool) contains the current tool name, and may be used by a user tool procedure overriding the default one in "tools.tcl".
