Hardware ILA data.
Usage
Name | Description |
---|---|
[-of_objects]
|
Get 'hw_ila_data' objects of these types: 'hw_ila hw_device'. |
[-regexp]
|
Patterns are full regular expressions |
[-nocase]
|
Perform case-insensitive matching. (valid only when -regexp specified) |
[-filter]
|
Filter list with expression |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
[<patterns>]
|
Match the 'hw_ila_data' objects against patterns. Default: * |
Description
Returns the ILA data objects in the Vivado logic analyzer.
The upload_hw_ila_data
command creates a hw_ila_data object in the process of moving the captured data from the ILA debug core, hw_ila, on the physical FPGA device, hw_device. The read_hw_ila_data
command can also create a hw_ila_data object when reading an ILA data file from disk.
The hw_ila_data object can be viewed in the waveform viewer of the Vivado logic analyzer by using the display_hw_ila_data
command, and can be written to disk using the write_hw_ila_data
command.
This command returns a list of available hardware ILA data objects, or returns an error if it fails.
Arguments
-of_objects <arg>
- (Optional) Return the hw_ila_data objects of the specified hw_ila debug objects. The hw_ila cores must be specified as objects using the get_hw_ilas
or the current_hw_ila
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_ila_datas
based on property values on the hardware ILA data objects. You can find the properties on an object with the report_property
or list_property
commands. In the case of the "hw_ila_data" object, "NAME" and "TIMESTAMP" 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_ila_data objects against the specified patterns. The default pattern is the wildcard '*' which gets a list of all hw_ila_data objects available in the Vivado logic analyzer.
Example
get_hw_ila_datas -of_objects [get_hw_ilas]
