The Scratch Pad is updated as changes are made to the loaded checkpoint. See the following figure. The Object Name column displays hierarchical names of Cells, Nets, Ports, and Pins. The Connectivity (Con) column tracks the connectivity of the objects and the Place and Route (PnR) column tracks the place and route status of the objects. In the Scratch Pad shown in the following figure, notice that check marks in the Con and PnR columns identify connectivity and place/route status. Looking at this figure, you can identify the following:
- The port ingressFifoWrEn_debug has been added and assigned to a package pin.
- The net ingressFifoWrEn has been connected to the newly created Port, but the connection has not yet been routed to the port.
