A post-synthesis project begins with a synthesized netlist, fully generated block designs, fully generated IP, and corresponding constraints. You can then analyze, floorplan, and implement the design.
Note: You can use either XST or third-party synthesis tools to create the synthesized netlist.
Important: When working with EDIF and NGC files, the top cell name must match the name of the file.
- Follow the steps in Creating a Project.
- In the Project Type page, select Post-Synthesis Project, and click Next.
Note: If necessary, you can select Do not specify sources at this time. This skips the steps of adding design sources and enables you to select the target part and create the project.
- In the Add Netlist Sources page, use the following options to specify netlist
files to read, identify the file containing the top module, and define
directories to search for lower-level module netlist, and click Next.
- Add Files
- Invokes a file browser so you can select netlist files (structural
Verilog, SystemVerilog, EDIF or NGC), BD Files, and XCI files (all
the output products for the IP must be generated, including the
DCP), or design checkpoint files (DCP) to add to the project. Recommended: Always reference the IP using the XCI file. Always reference a Block Design using the BD file; it is not recommended to read only the IP or BD DCP file. While the DCP does contain constraints, it does not provide other output products that an IP or BD could deliver and that could be needed, such as ELF, COE, and Tcl scripts.Note: Enable the Top radio button for the file that contains the top-level netlist.
- Add Directories
- Invokes a directory browser so you can select directories to search for modules. Files in the specified directory with valid source file extensions are added to the project.
- The button removes the selected source files and directories from the list.
- Move Up / Move Down
- Moves the file or directory up/down in the list order. The order of the files affects the processing order.

- Copy Sources into Project
- Copies files into the local project directory instead of referencing the original files. If you added directories of source files using Add Directories, the directory structure is maintained when the files are copied locally into the project. For more information, see Using Remote Sources or Copying Sources into Project.
- Add Sources from Subdirectories
- Looks for netlist files in the subdirectories of directories specified with Add Directories.
- Optional: In the Add Constraints page, set the following options, and click
- Add Files
- Invokes a file browser so you can select SDC or XDC files to add to the project.
- Create File
- Creates a new top-level XDC file for the project.
- Removes the selected file from the constraint list.
- Move Up / Move Down
- Moves a constraint file up or down in the listed order. Commands are order-dependent; the last-read command of a constraint overwrites the effects of an earlier command.
Note: Any SDC or XDC file found in the same directories as the RTL or netlist source files associated with the project are automatically listed as constraint files to be added to the project.
- Copy Constraints into Project
- Copies constraint files into the local project directory instead of referencing the original files.
- In the Default Part page, select a Xilinx part or TDP board,
and click Next:
- Lists available devices. Information about the device resources displays in a table view. You can filter the list using the Product Category, Family, Sub-Family, Package, Speed Grade, and Temp Grade filters. You can also use the Search field to find specific devices.
- Lists available TDP boards, and the Xilinx part used on the board. Information about device resources displays in a table view, such as I/O pin count, the number of LUTs and flip-flops, and available block RAM. You can filter the list using the Vendor, Display Name, and Board Rev filters. You can also use the Search field to find specific board parts.
- In the New Project Summary page, view the selected options that define the project, and click Finish.
