Usage
| Name | Description |
|---|---|
[-of_objects]
|

|
Perform case-insensitive matching. (valid only when -regexp specified) |
[-filter]
|
Filter list with expression |

Ignore command errors |

Suspend message limits during command execution |

Description
Returns the available hardware targets of the connected hardware servers.
The hardware target is a system board containing a JTAG chain of one or more Xilinx devices that you can program with a bitstream file, or use to debug your design. Connections between hardware targets on the system board and the Vivado Design Suite are managed by the Xilinx hardware server application, and the connect_hw_server command. Refer to Vivado Design Suite User Guide: Programming and Debugging (UG908) for a list of supported JTAG download cables and devices.
Use the open_hw_target command to open a connection to one of the available hardware targets. The open target is automatically defined as the current hardware target. Alternatively, you can define the current target with the current_hw_target command, and then open a connection to the current target. The Vivado Design Suite directs programming and debug commands to the open target through the hardware server connection.
This command returns a list of available hardware targets through all connected hardware servers, or returns an error if it fails.
Arguments
-of_objects <arg> - (Optional) Return the hardware targets of the specified hardware server. The hardware server must be specified as a hw_server object using the get_hw_servers commands.
-of_objects option requires objects to be specified using the get_* commands, such as get_cells or get_pins, rather than specifying objects by name. In addition, -of_objects cannot be used with a search <pattern>.
-regexp - (Optional) Specifies that the search <patterns> are written as regular expressions. Both search <patterns> and -filter expressions must be written as regular expressions when this argument is used. Xilinx regular expression Tcl commands are always anchored to the start of the search string. You can add ".*" to the beginning or end of a search string to widen the search to include a substring. See http://perldoc.perl.org/perlre.html for help with regular expression syntax.
regexp is not anchored, and works as a standard Tcl command. For more information refer to http://www.tcl.tk/man/tcl8.5/TclCmd/regexp.htm.
-nocase - (Optional) Perform case-insensitive matching when a pattern has been specified. This argument applies to the use of -regexp only.
-filter <args> - (Optional) Filter the results list with the specified expression. The -filter argument filters the list of objects returned by get_hw_targets based on property values on the targets. You can find the properties on an object with the report_property or list_property commands. In the case of the "hw_target" object, "NAME" and "IS_OPENED" are two of the properties that can be used to filter results.
get_pins * -filter {DIRECTION == IN && NAME !~ "*RESET*"}
bool) type properties can be directly evaluated in filter expressions as true or not true: -filter {IS_PRIMITIVE && !IS_LOC_FIXED}
-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.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config command.<patterns> - (Optional) Match hw_targets against the specified patterns. The default pattern is the wildcard '*' which gets a list of all hw_targets available on the connected hardware server.
