Interface Net objects. Returns nothing if the command fails.

DescriptionGets a list of interface nets in the current hardware design that match a specified search pattern. The default command gets a list of all interface nets in the subsystem design.
-regexp– (optional) Specifies that the search <patterns> are written as regular expressions. Both search <patterns> and
-filterexpressions 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 this web page for help with regular expression syntax.
regexpis not anchored, and works as a standard Tcl command. For more information, refer to this web page.
-filter <args> – (optional) Filter the
results list with the specified expression. The
argument filters the list of objects returned based on property values on
the objects. You can find the properties on an object with the
*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.
*wildcard character, this matches a property with a defined value of "".
For string comparison, the specific operators that can be
used in filter expressions are
!~). Numeric comparison
>= can also be used.
Multiple filter expressions can be joined by
For hardware design nets you can use the "NAME" property to filter results.
(optional) Get interface nets from all levels of hierarchical cells.
(optional) Used when source object is on a hierarchical block's pin. Valid values
are 'upper', 'lower', or 'both'. If 'lower' boundary, searches from the lower level
of hierarchy onwards. This option is only valid for connected_to relations.
-of_objects<args> - (optional) Get a list of the nets connected to the specified IP integrator subsystem cell, pin, or port objects.
-of_objectsoption requires objects to be specified using the
get_*commands, such as
get_pins, rather than specifying objects by name. In addition,
-of_objectscannot be used with a search pattern.
-quiet– (optional) Execute the command quietly, returning no messages from the command. The command also returns
TCL_OKregardless of any errors encountered during execution.
-verbose– (optional) Temporarily override any message limits and return all messages from this command.
<patterns> - (optional) Match hardware design interface nets against the specified patterns. The default pattern is the wildcard `*` which returns a list of all interface nets in the current IP integrator subsystem design. More than one pattern can be specified to find multiple nets based on different search criteria.
The following example gets the interface net attached to the specified pin of an hardware design, and returns the net:
hsi::get_intf_nets -of_objects [get_pins aclk]
