Usage
| Name | Description |
|---|---|
[-target_address_space]
|
Target address space to place segment into |
[-boundary]
|
assign peripherals to the exported slave hierarchical boundary of the design |
[-master_boundary]
|
set hierarchical master boundary by assigning exported master interface segments to internal masters |
[-external]
|
allow an external master interface to be mapped to more than one address |
-dict
|
dictionary of offset range address pairs, e.g. {offset 0x00000000 range 32K offset 0x20000000 range 32K} used to map an external interface to more than one address |
[-import_from_file]
|
import the addressing from file. When extension is csv, format = <address space name>,<slave segment>,<offset>,<range> |
[-export_to_file]
|
export the address map to a file in csv format. format = <address space name>,<slave segment>,<offset>,<range> |
[-export_gui_to_file]

[-offset]
|
Offset of assignment. e.g. 0x00000000 |
[-range]
|
Range of assignment. e.g. 4096, 4K, 16M, 1G |
[-base_high]

colon separated base:high offsets of a range assignment. e.g. 0x0000:0xFFFF |
[-force]
|
force the assignment, do not run any validity checks |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
[<objects>]
|
The objects to assign |

Description
Assign unmapped IP address segments to address spaces in the IP integrator subsystem design.
If the target address space is not specified, the IP integrator will automatically assign the address segment to an available address space on a connected AXI master.
If no bd_addr_seg objects are specified the assign_bd_address command will assign all unmapped address segments to any connected AXI master address spaces.
This command returns the newly mapped address segments, or returns an error if it failed.
Arguments
-target_address_space <arg> - (Optional) The target address space to place the segment into.
-boundary - (Optional) Assign address spaces to the hierarchical boundary of the design. This lets you allocate address space for memory that exists outside of the block design. Map scoped external slave interfaces into the address space at contiguous offsets beginning at 0x000_0000.
-master_boundary - (Optional) For the scoped external master interfaces, a slave segment is created is mapped into internal masters on the scoped diagram, at the specified -offset and -range.
-external - (Optional) Define memory segment of a previously defined external address space. Multiple memory segments can be assigned to an external AXI port that connects to a Slave IP outside of the BD.
-import_from_file <arg> - (Optional) Read address space assignments from a specified CSV format file containing a memory map. The CSV file must be in the form <address space name>,<slave segment>,<offset>,<range>. This command will overwrite any existing address space definition if the CSV file contains a valid address map. Otherwise the command will return an error.
-export_to_file <arg> - (Optional) Write address space assignments to a specified CSV format file. The CSV file will be in the form <address space name>,<slave segment>,<offset>,<range>. This command will not overwrite an existing file of the same name, unless -force is also specified.
-force - (Optional) Overwrite an existing CSV file when used with the -export_to_file option.
-base_high <arg> - (Optional) Assign the address space by specifying the <base address>:<high address>, in the form -base_high 0x4000_0000:0x4000_FFFF for instance.
-offset <arg> - (Optional) Specify the memory offset of address space to assign the address segment to. For example, 0x00000000.
-range <arg> - (Optional) Range, or size, of address space to assign the address segment into. For example 4096, 4K, 16M, 1G.
-dict <arg> - (Optional) A dictionary of Offset/Range value pairs to be defined at one time. The format of the offset/range value pair is as follows:
-dict {offset 0x00000000 range 64M offset 0x20000000 range 64M}-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.<objects> - The block design address segment objects to assign to the target address space.
