  - Click on **Add Sources** just like in the [[tutorials:creating_a_new_module]] tutorial.  However, this time select **Add or create Constraints**.  Click **next**.
  - Click **Create File...** \\ Ensure that File Type is **XDC** and that File Location is set to **Local to Project**. Enter a name for the XDC file and click **OK**.
  - Your new XDC file is located in the **Project Manager**, in the **sources** pane, inside the **Constraints** folder. Find the file and double click it to open it.
