Description

Get a list of memory ranges.

Syntax

get_mem_ranges [-regexp] [-filter <arg>] [-hierarchical] [-of_objects <args>] [-quiet] [-verbose] [<patterns>...]

Returns

Memory range objects. Returns nothing if the command fails.

Usage

Name Description
[-regexp] Patterns are full regular expressions
[-filter] Filter list with expression
[-hierarchical] Get memory ranges from all levels of hierarchical cells
[-of_objects] Get 'mem_range' objects of these types: 'cell'.
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution
[<patterns>] Match cell names against patterns Default: *

Description

Get a list of slaves of the processor in the current hardware design.

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 this web page 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 this web page.

-filter <args> – (optional) Filter the results list with the specified expression. The -filter argument filters the list of objects returned based on property values on the objects. You can find the properties on an object with the report_property or list_property commands.

Quote the filter search pattern to avoid having to escape special characters that might 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 matches 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 ||).

-hierarchical - (optional) Get memory ranges from all levels of hierarchical cells.

-of_objects <arg> - (optional) Get the slaves of the specified object.

-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 are returned. Only errors occurring inside the command are 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 address segments against the specified patterns. The default pattern is the wildcard `*` which gets a list of all address segments in the current IP subsystem design. More than one pattern can be specified to find multiple address segments based on different search criteria.

Note: You must enclose multiple search patterns in braces {} to present the list as a single element.

Examples

The following example gets the slaves of the processor: 

hsi::get_mem_ranges
hsi::get_mem_ranges -of_objects [lindex [get_cells -filter {IP_TYPE==PROCESSOR} ] 0]
Note: If there are no objects matching the pattern you will get a warning.
