When both the Layout Editor and the Schematic Editor are displaying the same design, select one or more component instances and interface ports in both editors. Select the schematic elements or layout elements to be cross-probed. Then use one of the following methods to effect the cross-selection:
- In either editor, press Ctrl +K.
- In the Schematic Editor, select Schematic > Cross-Probe Layout.
- In the Layout editor, select Layout > Cross-Probe Schematic.
The corresponding elements in the related editor is selected and that editor window is brought to the front. If you select only component instances or only interface ports, then after cross-probing the primary selection in the first editor is also the primary selection in the related editor. Note that all previous selections in the related editor is cleared and only the cross-probed elements is selected when the command is invoked.
Changes to a design should be made on the editor that was used to create the design. For example, if a design was created using the Schematic Editor, it should not be modified on the layout editor. In some cases, attempts to change a schematic design on the Layout Editor results in a warning such as:
[warning] Port Port2, ID %2, was disconnected from net 98, but it was not possible to unwire it. This must be done manually.
Similarly, a Layout Editor design can be viewed as a schematic using the cross-probing feature, but the schematic view should not be used to make changes to the design. Although an operation such as deleting a port in the schematic may successfully delete the cross-probed layout port, the operation cannot be undone in the Layout Editor after the schematic window has been closed (the undo attempt may cause an error).
