Syntax
get_hw_sio_linkgroups [‑of_objects <args>] [‑regexp] [‑nocase]
[‑filter <arg>] [‑quiet] [‑verbose] [<patterns>]
Returns
hardware SIO link groups
Usage
Name | Description |
---|---|
[-of_objects]
|
Get 'hw_sio_linkgroup' objects of these types: 'hw_sio_link'. |
[-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_sio_linkgroup' objects against patterns. Default: * |
Description
Returns the defined groups, or associations of communication links between TX and RX objects on the GTs of the IBERT debug core defined on the current hardware device.
Vivado Serial I/O analyzer is a link-based analyzer. The links define the communication paths and protocols between transmitters and receivers of the GigaBit transceivers on the device. Link groups, or hw_sio_linkgroup objects, let you associate links into related groups, to collectively configure properties and run scans.
This command returns a list of linkgroups on the IBERT debug core, or returns an error if it fails.
Arguments
-of_objects
<arg> - (Optional) Return the linkgroup objects of the specified hw_sio_links. The links must be specified as objects using the get_hw_sio_links command
.
-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_sio_linkgroups
based on property values on the link groups. You can find the properties on an object with the report_property
or list_property
commands. In the case of the "hw_sio_linkgroup" object, "NAME" and "DESCRIPTION" 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_sio_linkgroup objects against the specified patterns. The default pattern is the wildcard '*' which gets a list of all hw_sio_linkgroups available on the current hardware device.
