Placing Devices Interactively in the Automated Device Placement and Routing Flow

To run the device-level interactive placer:

Open the Place tab of the Auto P&R assistant.
Select the Context Menu icon in the toolbar to display a shortcut menu whenever one or more devices are selected in the layout canvas. You can perform context-sensitive operations on devices and device groups directly in the layout canvas.
Select Highlight Virtual Groups to highlight all virtual groups in the layout canvas. The icon automatically changes to Dehighlight Virtual Group, which lets you remove the highlights.
Select Row Snapping to display row snapping-related details in the Information pane during interactive placement of devices.
Hover over devices to display a context-sensitive menu that provides interactive placement commands to refine placement of devices and device groups.
Select the required interactive placement commands.
