Editing In Place

Use the Edit In Place command to edit a placed instance in your design and maintain the connectivity. You can also use the Edit – Hierarchy – Descend command to descend into an instance.

When you choose Edit In Place (or Descend), by default, Layout XL opens the connectivity reference for the cell into which you are descending. To prevent this, switch off the Open connectivity reference option on the General of the Connectivity form. When switched off, the layout cellview is still opened in Layout XL mode, but with no connectivity reference.

To edit a placed instance in your design,

1. Choose Edit – Hierarchy – Edit In Place.
2. Click the instance whose cell you want to edit.
   The banner at the top of the window changes to show that you are now editing the master cell for that instance. Notice the instance is highlighted along the border.
   Instances with placement status unplaced are not visible in the layout canvas, and so do not contribute to the floorplanning estimations. When one or more such instances are found in a design, a dialog box indicating their presence is displayed, prompting whether these instances should be made visible. If you click Yes, the placement status of these instances is changed to none, making them visible in the layout canvas. If you click No, the dialog box is closed without making any changes.
3. When you have finished editing, choose Edit – Hierarchy – Return to stop editing in place.
   Layout XL returns you to the next level of the hierarchy.
   To specify the level of hierarchy to return to, choose Edit – Hierarchy – Return To Level.
