Open a Vivado project file (.xpr)


open_project [‑part <arg>] [‑read_only] [‑quiet] [‑verbose] <file>


Opened project object.


Name Description
[-part] Open the project using this part (overrides project's part)
[-read_only] Open the project in read-only mode
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution
<file> Project file to be read




Opens the specified Vivado® Design Suite project file (.xpr), or the project file for the Vivado Lab Edition (.lpr).

Important: The open_project command has a different command syntax in the Vivado Lab Edition. The -part option is not supported because the Vivado Lab Edition project (.lpr) does not specify a target part. The current_hw_target and current_hw_device commands determine the target part.

This command returns a transcript of its process and the name of the created project, or returns an error if it fails.


-part <arg> - (Optional) Specify a target part to use when opening the project. This option lets you change the speed grade of the part used by a saved project, or change early availability parts for production parts of the same device and package. This option is not supported in Vivado Lab Edition.
Important: The use of -part is limited in terms of the range of parts that can be used, and can result in an error when opening the project if an incompatible part is specified.

-read_only - (Optional) Open the project in read only mode. You will not be able to save any modifications to the project unless you use the save_project_as command to save the project to a new editable project.

-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.

<file> - (Required) The project file to open. You must include both the path to the file and the .xpr file extension.


The following example opens the project named my_project1 located in the Designs directory.
open_project C:/Designs/project1.xpr
Note: The project must be specified with the .xpr extension for the tool to recognize it as a project file. The path to the file must be specified along with the project file name or the tool will return an error that it cannot find the specified file.
