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.
