Hardware cfgmems
Usage
| Name | Description |
|---|---|
[-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_cfgmem' objects against patterns. Default: * |
Description
Get a list of hardware configuration memory (hw_cfgmem) objects created for the current hw_device.
Xilinx® FPGAs are configured by loading design-specific configuration data, in the form of a bitstream file, into the internal memory of the hw_device. The hw_cfgmem defines a flash memory device used for configuring and booting the Xilinx FPGA device. Once the hw_cfgmem object is created, and associated with the hw_device, the configuration memory can be programmed with the bitstream and other data using the program_hw_cfgmem command.
The hw_cfgmem object is associated with the specified hw_device object through the PROGRAM.HW_CFGMEM property on the device object. The get_hw_cfgmems command lets you work with the hw_cfgmem object.
This command returns a list of hw_cfgmem objects that match the specified search criteria, or returns an error if it fails.
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.
-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_cfgmems based on property values on the hw_cfgmem objects. You can find the properties on an object with the report_property or list_property commands.
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_cfgmems against the specified patterns. The default pattern is the wildcard '*' which gets a list of all hw_cfgmems currently defined.
