When you open an implemented design in the Flow Navigator, the Vivado IDE opens the implemented netlist and applies the physical and timing constraints used during implementation, placement, and routing results against the implemented part. The placed logic and routed connections of the implemented design are loaded into memory, and you can analyze and modify the elements as needed to complete the design. You can save updates to the constraints files, netlist, implementation results, and design configuration. Because the Vivado IDE allows for multiple implementation runs, you can select any completed implementation run to open the implemented design.
In an implemented design, you can perform many design tasks, including timing analysis, power analysis, and generation of utilization statistics, which can help you determine if your design converged on desired performance targets. You can explore the design in a variety of ways using the windows in the Vivado IDE. Selected objects are always cross-selected in all related windows. You can cross probe to lines in the source RTL files from various windows, including the Messages, Schematic, Device, Package, and Find windows. The Schematic window allows you to interactively explore the logic interconnect and hierarchy. You can also apply timing constraints and perform further timing analysis. In addition, you can interactively apply floorplanning or design configuration constraints and save the constraints for future runs. For more information, see the Vivado Design Suite User Guide: Design Analysis and Closure Techniques (UG906).
In the Device window, you can explore the placement or the routing results by toggling the Routing Resources button . As you zoom, the amount of detail shown in the Device window increases. You can interactively alter placement and routing as well as design configuration, such as look-up table (LUT) equations and random access memory (RAM) initialization. You can also select results in the Device or Schematic windows to cross probe back to problem lines in the RTL files. In the Schematic window, you can interactively explore the logic interconnect and hierarchy. For more information, see the Vivado Design Suite User Guide: Design Analysis and Closure Techniques (UG906).
To open an implemented design, use one of the following methods:
- In the Implementation section of the Flow Navigator, click Open Implemented Design.
- Select .
- In the Design Runs view, double-click the run name.
The following figure shows the default layout view for an open implemented design.
