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 |
[-verbose]
|
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.
