The Hard Block Planner window allows you to place the hard blocks within a device, and provides a visual feedback in the Device window for assigning the location of the REFCLK pins, the GT_QUADs, and the Hard-IP blocks. Once you open the synthesized design, it reads and processes the netlist objects and collects all hard IPs available in a design. The Hard Block Planner window groups GT_QUADs under Hard-IPs, such as PCIe and DCMAC. It also lists the soft IPs and standalone GTs in the design under a separate drop-down menu, alongside the hard IPs, to facilitate the planning of GT blocks. This planner allows you to cross-probe the location in the Device window view for changing or assigning the site.
To view the Hard Block Planner window, open Synthesized/Implemented design. The Hard Block Planner window opens by default after opening Synthesized/Implemented design. Alternately, it can be opened from the Windows menu.
