7.4.1. Creating Clock Assignments with the Chip Planner
- Select the Create Clock Assignment
icon, OR click View > Clock Assignments > Create Clock Assignment.
- Click and drag on the Chip Planner floorplan to create a clock region of your preferred location and size. The region that you draw snaps to the smallest clock sector capable of containing the region. During interactive clock assignment operations such as creating, moving, or resizing, clock sector grids are shown in orange to facilitate positioning of the clock region relative to the clock sectors.
A clock symbol in the region title bar identifies it as a clock region. By default, the newly created clock region has the name unassigned, until you assign a clock signal from the context menu.
