The Floorplanner View has two modes of operation:

You can also view properties of selected macros in the Floorplanner View from the properties window. You can select multiple macros from the Floorplanner View by pressing the CTRL key and selecting required macros in the Floorplanner View.
• Region Manipulation Mode. Use this mode to work on regions such as resizing, renaming, or deleting regions, or assigning and unassigning macros or nets to regions.

Click the Macro Manipulation Mode or Region Manipulation Mode button to switch between modes.

The icons available at the top of the Floorplanner View window allow you to zoom in, zoom out, assign I/ O banks, runs DRC checks, and create regions for placement.

also appears in the toolbar. The following table lists the functions of each icon.
