Enabling Level-1 Editing Mode

Level-1 Editing mode is the ability to edit objects inside a soft block without using the Descend or Edit In Place commands.

While in level-1 editing mode, you can edit the objects placed at level-1 only if the top-level is selectable.

To enable Level-1 Editing mode,

From the layout window menu bar, choose Options – Display.
The Display Options form appears.
In the Display Controls group box, under Display Levels, set the Stop value to 1.
In the Objects panel, check the V and S check box to make Pins, P&R Boundary, and Snap Boundary visible and selectable. Check the S check box to make Soft Block Pins, P&R boundary, and Snap Boundary selectable.

If an instance bounding box fully overlaps the place and route boundary, you need to click the instance twice in order to select the place and route boundary. The first click selects the instance, and the second click selects the Level-1 place and route boundary.

Once in Level-1 Editing mode, you can do the following.
