Usage
Name | Description |
---|---|
[-of_objects]
|
Get 'hw_sio_sweep' objects of these types: 'hw_sio_link hw_sio_scan'. |
[-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 |

Suspend message limits during command execution |
[<patterns>]

Match the 'hw_sio_sweep' objects against patterns. Default: * |
Description
Return the serial I/O analyzer link sweep objects defined on the IBERT debug core.
To analyze the margin of a given link, it is often helpful to run a scan of the link using the specialized features of Xilinx® UltraScale™ devices or 7 series FPGAs. It can also be helpful to run multiple scans on a the link with different configuration settings for the GTs. This can help you determine which settings are best for your design. The Vivado® serial I/O analyzer feature enables you to define, run, and save link sweeps, or collections of link scans run across a range of values.
This command returns a link sweep object that you can use with the run_hw_sio_sweep
command to run analysis on the specified links, or GT receivers. You can also save the sweep scan to disk using the write_hw_sio_sweep
command.
You can remove the created sweep object using remove_hw_sio_sweep
.
This command returns one or more hw_sio_sweep objects, or returns an error if the command fails.
Arguments
-of_objects <arg>
- (Optional) Return the serial I/O analyzer sweep object of the specified hw_sio_link or hw_sio_scan. The objects must be specified using the appropriate get_hw_*
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_sweeps
based on property values on the hw_sio_sweep objects. You can find the properties on an object with the report_property
or list_property
commands. In the case of the "hw_sio_sweep" 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_sweep objects against the specified patterns. The default pattern is the wildcard '*' which gets a list of all hw_sio_sweeps available on the current hardware device.
