Once you have completed design entry and are ready for physical implementation of the design, you begin implementation processing by clicking the Implementation button on the project flowchart. All the steps needed to obtain the final results are invoked automatically. Refer to the “Design Implementation” chapter for more information.
Typically, designs are implemented by using the Implementation button on the project flowchart. However, you can access certain specialized functions from the Project Manager Tools menu.
The Flow Engine processes the design, controls the implementation of the design, and guides the implementation revisions. When initiated by selecting Tools 
Implementation Flow Engine, the Flow Engine is run as a standalone program. The project is not automatically brought up-to-date as it is when initiated by the Implementation button on the project flowchart. For more information, see the “Implementing a Design” section of the “Design Implementation” chapter.
Selecting Tools Implementation Floor Planner from the Project Manager window, accesses the Floorplanner tool (for FPGAs only).The Floorplanner creates a file that contains mapping information, which can be used by the Flow Engine as a guide for mapping an FPGA implementation revision.
For more information on the Floorplanner, see the DynaText online document, Floorplanner Reference/User Guide.
Selecting Tools Implementation EPIC Design Viewer/Editor from the Project Manager window opens the EPIC Design Editor. EPIC provides a graphic view of your placed and routed design, allowing you to make modifications. This option is supported for FPGAs only.
For more information on using the EPIC Design Editor, see the DynaText online document, EPIC Reference Guide.
I/O pins can be locked to a previous revision by clicking on the revision in the Versions tab of the Project Manger and selecting Tools Implementation Lock Device Pins. The Lock Pins Status dialog appears upon completion. You can click View Lock Pins Report from the Lock Pin Status dialog or select Tools Implementation View Locked Pins Report to access the Lock Pins Report. The Lock Pins Report contains information on any constraint conflicts between the pin locking constraints in the existing UCF file and the design file.
