get_keepers (::quartus::sdc

Tcl Package and Version

Belongs to ::quartus::sdc_ext 2.0

Syntax

get_keepers [-h | -help] [-long_help] [-no_duplicates] [-nocase] [-nowarn] [ <filter> ]

Arguments

-h | -help

Short help

-long_help

Long help with examples and possible return values

-no_duplicates

Do not match duplicated keeper names

-nocase

Specifies the matching of node names to be case-insensitive

-nowarn

Do not issue warning messages about unmatched patterns

<filter>

Valid destinations (string patterns are matched using Tcl string matching)

Description

Returns a collection of non-combinational or "keeper"
nodes in the design.

The default matching scheme returns not only
non-combinational nodes whose names match the
specified filter, but also non-combinational nodes
duplicated from these keepers (refers to cells are
automatically generated by Quartus from these
keepers).  Use the -no_duplicates option to exclude
duplicated keepers.

The filter for the collection is a Tcl list of
wildcards, and must follow standard Tcl or
Timing Analyzer-extension substitution rules. See help for
the use_timing_analyzer_style_escaping command for details.
