Syntax
get_pblocks [‑regexp] [‑nocase] [‑filter <arg>] [‑of_objects <args>]
[‑include_nested_pblocks] [‑quiet] [‑verbose] [<patterns>]
Returns
List of Pblock objects.
Usage
Name | Description |
---|---|
[-regexp]
|
Patterns are full regular expressions |
[-nocase]
|
Perform case-insensitive matching (valid only when -regexp specified) |
[-filter]
|
Filter list with expression |
[-of_objects]
|
Get Pblocks of these cells |
[-include_nested_pblocks]
|
Display the the list of nested pblocks |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
[<patterns>]
|
Match Pblock names against patterns Default: * |
Description
Gets a list of Pblocks defined in the current project that match a specific pattern. The default command gets a list of all Pblocks in the project.
get_*
commands return a container list of a single type of objects (e.g. cells, nets, pins, or ports). You can add new objects to the list (using lappend
for instance), but you can only add the same type of object that is currently in the list. Adding a different type of object, or string, to the list is not permitted and will result in a Tcl error.
Arguments
-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_pblocks
based on property values on the Pblocks. You can find the properties on an object with the report_property
or list_property
commands. In the case of the Pblock object, "NAME" and "GRID_RANGES" are some 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}
-of_objects <arg>
- (Optional) Get the Pblocks to which the specified cells are assigned.
-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>
.
-include_nested_pblock
- (Optional) Also get and return any Pblocks nested inside the group of Pblocks returned by the specified search. The nested Pblocks will be added to the list of Pblock objects returned by this command. Refer to the create_pblock
command for an example of nesting Pblocks.
-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 Pblocks against the specified patterns. The default pattern is the wildcard '*' which returns all Pblocks in the project.
Examples
The following example gets a list of all Pblocks in the current project:
get_pblocks
This example gets a list of all Pblocks which do not have a Slice Range defined:
get_pblocks -filter {GRIDTYPES !~ SLICE}
The following example gets the Pblock assignments of the specified cell:
get_pblocks -of [get_cells CORE/BR_TOP/RLD67_MUX/REG_PMBIST_C1]
This example returns the specified Pblock, including any nested Pblocks:
get_pblocks -include_nested_pblocks usbTop
