Tcl Package and Version

Belongs to ::quartus::sdc_ext

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.
