21.8.9 create_set
(Ask a Question)Description
Creates
a set of paths to be analyzed. Use the arguments to specify which paths to include.
To create a set that is a subset of a clock domain, specify it with the
-clock and -type arguments. To create a set
that is a subset of an inter-clock domain set, specify it with the
-source_clock and -sink_clock arguments. To
create a set that is a subset (filter) of an existing named set, specify the set to
be filtered with the -parent_set argument.

source_clock <clock name>\ -sink_clock <clock name>\ -in_to_out\ -source <port/pin pattern> \
-sink <port/pin pattern>Arguments
| Parameter | Type | Description |
|---|---|---|
name | string | Specifies a unique name for the newly created path set. |
parent_set | string | Specifies the name of the set to filter from. |
clock | string | Specifies that the set is to be a subset of the given clock domain. This argument is valid only if you also specify the -type argument. |
type | string | Specifies the predefined set type on which to base the new path set. You can only use this argument with the -clock argument, not by itself.
|
in_to_out | None | Specifies that the set is based on the "Input to Output" set, which includes paths that start at input ports and end at output ports. |
source_clock | string | Specifies that the set will be a subset of an inter-clock domain set with the given source clock. You can only use this option with the -sink_clock argument. |
sink_clock | string | Specifies that the set will be a subset of an inter-clock domain set with the given sink clock. You can only use this option with the -source_clock argument. |
source | string | Specifies a filter on the source pins of the parent set. If you do not specify a parent set, this option filters all pins in the current design. |
sink | string | Specifies a filter on the sink pins of the parent set. If you do not specify a parent set, this option filters all pins in the current design. |

Example
The following example creates set with "my_user_set" name. Filters all C* ports and D* pins in the current design.
create_set -name { my_user_set } –source { C* } –sink { D* }The following example creates set with
my_other_user_set
name that is a subset (filter) of an existing "my_user_set"
set.
create_set -name { my_other_user_set } –parent_set { my_user_set } –source { CL* }The following example creates set with another_set name which is the subset of
an inter-clock domain set with the given source clock.
create_set -name { another_set } –source_clock { EXTERN_CLOCK } \
–sink_clock { MY_GEN_CLOCK }
