Description
Gets a list of I/O Banks on the target device in the current project that match a specified search pattern. The default command gets a list of all I/O Banks on the target device.
Note: To improve memory and performance, the
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.
Note: The Tcl built-in command
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_iobanks based on property values on the I/O Banks. You can find the properties on an object with the report_property or list_property commands. Some of the properties that can be used with for an iobank object include "BANK_TYPE", "DCI_CASCADE", and "INTERNAL_VREF".
The filter search pattern should be quoted to avoid having to escape special characters that may be found in net, pin, or cell names, or other properties. String matching is case-sensitive and is always anchored to the start and to the end of the search string. The wildcard “*” character can be used at the beginning or at the end of a search string to widen the search to include a substring of the property value.
Note: The filter returns an object if a specified property exists on the object, and the specified pattern matches the property value on the object. In the case of the "*" wildcard character, this will match a property with a defined value of "".
For string comparison, the specific operators that can be used in filter expressions are "equal" (==), "not-equal" (!=), "match" (=~), and "not-match" (!~). Numeric comparison operators <, >, <=, and >= can also be used. Multiple filter expressions can be joined by AND and OR (&& and ||). The following gets input pins that do NOT contain the “RESET” substring within their name:
get_pins * -filter {DIRECTION == IN && NAME !~ "*RESET*"}
Boolean (
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 a list of the I/O Banks connected to these objects. Valid object types are clock_regions, package_pins, ports, slrs and sites.
Note: The
-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>.
-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.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the
set_msg_config command.<patterns> - (Optional) Match I/O Banks against the specified pattern. The default pattern is the wildcard '*' which gets a list of all I/O Banks in the design.
Examples
The following example returns the I/O Bank of the specified package pin:
get_iobanks -of_objects [get_package_pins H4]This example returns the GT Banks on the device:
get_iobanks -filter {BANK_TYPE == BT_MGT}
