Usage
Name | Description |
---|---|

|
Perform case-insensitive matching. (valid only when -regexp specified) |
[-filter]
|
Filter list with expression |
[-of_objects]
|
Get the pin_nibble of these package_pins, iobank, site, or port. |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
[<patterns>]
|
Match pin_nibble against patterns Default: * |
Description
Return a list of nibbles, or half-bytes, on the I/O banks of the current Xilinx UltraScale device.
For 7 series devices, the hierarchy of IO Banks is divided into two object types: I/O Banks and Package Pins. For Xilinx UltraScale FPGA devices, the IO Bank hierarchy includes two additional divisions: Byte groups and Nibbles.
- An iobank has 2 or 4 bytegroups.
- Each pkgpin_bytegroup has 2 nibbles, an upper and lower, and has 13 package pins.
- Each pkgpin_nibble has 6 or 7 pins, and is the upper or lower nibble of the pkgpin_bytegroup.
- A package_pin is one pin of an iobank, a pkgpin_bytegroup, or a pkgpin_nibble.
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.
-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_pkgpin_nibbles
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 pkgpin_nibble object, "NAME", "IOBANK" and "TYPE" 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 pkgpin_nibble objects of the specified package_pins, iobank, site, or port.
-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 pkgpin_nibbles against the specified patterns. The default pattern is the wildcard '*' which returns all pkgpin_nibble objects on the current device.
Examples
get_pkgpin_nibbles -of [get_iobanks 44] -filter {TYPE == U}
