Description
Get a list of address spaces in the current IP integrator subsystem design.
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.
-hierarchical
- (Optional) Get address spaces from all levels of the IP integrator subsystem design hierarchy, or current instance. Without this argument, the command will only get address spaces from the top of the design hierarchy. When using -hierarchical
, the search pattern should not contain a hierarchy separator because the search pattern is applied at each level of the hierarchy, not to the full hierarchical name. For instance, searching for U1/* searches each level of the hierarchy for objects with U1/ in the name. This may not return the intended results.
-regexp
, the specified search string is matched against the full hierarchical name, and the U1/* search pattern will work as intended.
-filter
<args> - (Optional) Filter the results list with the specified expression. The -filter
argument filters the list of objects returned by get_bd_addr_spaces
based on property values on the objects. You can find the properties on an object with the report_property
or list_property
commands. In the case of the IP integrator address space object, "NAME", "RANGE" and "OFFSET" 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 address spaces of the specified IP integrator address segment, cell, or interface pin objects.
-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.
-verbose
- (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config
command.<patterns> - (Optional) Match address spaces against the specified patterns. The default pattern is the wildcard '*' which gets a list of all address spaces in the current IP subsystem design. More than one pattern can be specified to find multiple address spaces based on different search criteria.
Examples
The following example lists all of the address spaces in the current IP integrator subsystem design, listing one per line:
join [get_bd_addr_spaces] \n
/mdm_1/S_AXI
/microblaze_1/Data
/microblaze_1/Instruction
/microblaze_1_axi_intc/s_axi
/microblaze_1_local_memory/dlmb_bram_if_cntlr/SLMB
/microblaze_1_local_memory/dlmb_bram_if_cntlr/SLMB1
/microblaze_1_local_memory/dlmb_bram_if_cntlr/SLMB2
/microblaze_1_local_memory/dlmb_bram_if_cntlr/SLMB3
/microblaze_1_local_memory/dlmb_bram_if_cntlr/S_AXI_CTRL

The following example returns all of the properties attached to the third in a list, or index 2, of all address spaces in the current subsystem design:
report_property -all [lindex [get_bd_addr_spaces] 2 ]
Property Type Read-only Visible Value
CLASS string true true bd_addr_space
NAME string false true /microblaze_1/Instruction
OFFSET string false true
PATH string true true /microblaze_1/Instruction
RANGE string false true -1
TYPE string false true
