Get current value of the selected HDL object (variable, signal, wire, reg)
Syntax
get_value [‑radix <arg>] [‑quiet] [‑verbose] <hdl_object>
Returns
Returns a string representation of value of a hdl_object.
Usage
Name | Description |
---|---|
[-radix]
|
radix specifies the radix to use for printing the values of the hdl_objects. Allowed values are: default, dec, bin, oct,hex, unsigned, ascii, smag |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
<hdl_object>
|
The hdl_object to retrieve the current value |
Categories
Description
Get the value of a single HDL object at the current simulation run time.
report_values
command to return the values of more than one HDL objects.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 HDL scope, or scope, is defined by a declarative region in the HDL code such as a module, function, task, process, or begin-end blocks in Verilog. VHDL scopes include entity/architecture definitions, block, function, procedure, and process blocks.
Arguments
-radix <arg>
- (Optional) Specifies the radix to use when returning the value of the specified object. Allowed values are: default
, dec
, bin
, oct
, hex
, unsigned
, ascii
, or smag
.
dec
indicates a signed decimal. Specify the radix unsigned
when dealing with unsigned data.-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.<hdl_object> - (Required) Specifies a single HDL object to get the value of. The object can be specified by name, or can be returned as an object from the get_objects
command.
Examples
The following example gets the value of the sysClk signal:
get_value sysClk
Z
This example shows the difference between the bin
, dec
, and unsigned
radix on the value returned from the specified bus:
get_value -radix bin /test/bench_VStatus_pad_0_i[7:0]
10100101
get_value -radix unsigned /test/bench_VStatus_pad_0_i[7:0]
165
get_value -radix dec /test/bench_VStatus_pad_0_i[7:0]
