---|---|
[-of_objects]
|

Match the 'hw_sio_pll' objects against patterns. Default: * |
Description
Returns the PLL objects, hw_sio_pll, defined on the IBERT debug core on the current hardware device.
For each serial transceiver channel, there is a ring PLL called Channel PLL (CPLL). In AMD UltraScale™ and 7 series FPGAs, the GTX has an additional shared PLL per quad, or Quad PLL (QPLL). This QPLL is a shared LC PLL to support high speed, high performance, and low power multi-lane applications.
On the device, the GTXE2_CHANNEL component has the serial transceiver and CPLL units and the GTXE2_COMMON has the QPLL unit.
This command returns a list of all PLL objects, both CPLLs and QPLLs on the device, or returns an error if it fails.
Arguments
-of_objects <arg>
- (Optional) Return the PLL objects of the specified hw_server, hw_target, hw_device, hw_sio_ibert, hw_sio_gt, or hw_sio_common objects. The objects must be specified using the appropriate get_hw_*
command for the object.
-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_plls
based on property values on the PLLs. You can find the properties on an object with the report_property
or list_property
commands. In the case of the "hw_sio_pll" object, "NAME" and "PARENT" 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_pll objects against the specified patterns. The default pattern is the wildcard '*' which gets a list of all hw_sio_plls available on the current hardware device.
Example
The following example returns a list of the PLL objects on the IBERT debug core:
join [get_hw_sio_plls -of [get_hw_sio_iberts] ] \n
This example returns the PLL objects on the hw_sio_commons of the IBERT debug core:
join [get_hw_sio_plls -of [get_hw_sio_commons ]] \n
