Get a list of all input ports in the current design


all_inputs [‑quiet] [‑verbose]


List of port objects.


Name Description
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution




Returns a list of all input port objects in the current design.

To get a list of specific inputs in the design, use the get_ports command, or use the filter command to filter the results returned by all_inputs.

The all_inputs command is scoped to return the objects hierarchically, from the top-level of the design or from the level of the current instance. By default the current instance is defined as the top level of the design, but can be changed by using the current_instance command.


-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.


The following example returns all input port objects in the current design:


This example gets all input port objects, filters out the GT ports, and sets the IOSTANDARD property for the non-GT ports:

set non_gt_ports [filter [all_inputs] {!is_gt_term}]
set_property IOSTANDARD LVCMOS18 $non_gt_ports

The following example shows how the list returned can be passed to another command:

set_input_delay 5 -clock REFCLK [all_inputs]
