Syntax
get_hw_ddrmcs [‑of_objects <args>] [‑regexp] [‑nocase] [‑filter <arg>]
[‑quiet] [‑verbose] [<patterns>]
Returns
Integrated and soft DDRMC cores.
Usage
Name | Description |
---|---|
[-of_objects]
|
Get 'hw_ddrmc' objects of these types: 'hw_server hw_target hw_device'. |
[-regexp]
|
Patterns are full regular expressions |
[-nocase]
|
Perform case-insensitive matching. (valid only when -regexp specified) |
[-filter]
|
Filter list with expression |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
[<patterns>]
|
Match the 'hw_ddrmc' objects against patterns. Default: * |
Description
Versal devices include integrated DDR Memory Controllers (DDRMC), as well as fabric based memory controllers. Refer to the Versal Adaptive SoC Programmable Network on Chip and Integrated Memory Controller LogiCORE IP Product Guide (PG313) for more information on the integrated controller core. Refer to Versal ACAP Soft DDR4 Memory IP (PG353) for more information on the fabric based memory controller. The memory controllers contain memory configuration and memory calibration data that can be accessed from the AMD Vivado™ Hardware Manager. The calibration and margin data are organized and presented in a graphical format for ease of analysis.
The get_hw_ddrmc
command returns a list of memory cores on the current hardware device.
Arguments
-of_objects <arg>
- (Optional) Return the Versal Memory controller (DDRMC) objects of the specified hw_server, hw_target, or hw_device 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>
.
-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.
-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_hw_ddrmcs
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 hw_ddrmc object, "MEM_TYPE" and "BITS_PER_BYTE", are examples of couple 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}
-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 hw_ddrmc objects against the specified
patterns. The default pattern is the wildcard `*` which gets a list of all hw_ddrmc
available on the current hardware device.
Examples
The following example returns the HBM with the specified DISPLAY_NAME:
get_hw_hbms -filter {DISPLAY_NAME == HBM_2}
The following example returns the DDRMC with the specified DISPLAY_NAME:
get_hw_ddrmcs -filter {DISPLAY_NAME == DDRMC_1}
