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. |
