Print details of the given hdl objects (variable, signal, wire, or reg)


report_objects [‑quiet] [‑verbose] [<hdl_objects>...]


Print name, type, data_type of the HDL objects on console in textual format.


Name Description
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution
[<hdl_objects>] The hdl_objects to report. Default is report_objects [get_objects *]



The report_objects command reports the type, name, and language of the specified HDL objects to the Tcl Console or Tcl shell. You must have an open simulation to use this command.

This command returns a brief description of the specified objects. Use the describe command to return more detailed information.

HDL objects include HDL signals, variables, or constants as defined in the Verilog or VHDL test bench and source files. An HDL signal includes Verilog wire or reg entities, and VHDL signals. Examples of HDL variables include Verilog real, realtime, time, and event. HDL constants include Verilog parameters and localparams, and VHDL generic and constants.

The command returns the HDL object type, the name, and the code type (Verilog/VHDL) for each object, or returns an error if it fails.


-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.

<hdl_objects> - (Optional) Specifies the objects to report. The default command reports all objects found in the current scope of the simulation, or current_scope.

Note: Objects can be specified by name, or returned as objects by the get_objects command.


The following example shows how the specified objects reported depend upon the current scope of the simulation:

current_scope testbench
report_objects [get_objects leds_n]
  Declared: {leds_n[3:0]}                  Verilog
current_scope dut
report_objects leds_n
       Out: {LEDS_n[3:0]}                  VHDL

This example reports the specified HDL objects of the current simulation scope:
