Arguments | -h | -help | Short help | ||
-long_help | Long help with examples and possible return values | |||
-no_duplicates | Do not match duplicated net names | |||
-nocase | Specifies case-insensitive node name matching | |||
-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 nets in the design. All net names in the collection match the specified pattern. Wildcards can be used to select multiple nets at once. The default matching scheme returns nets whose names match the specified filter and nets that are automatically generated by the Quartus Prime software from these nets. Use the -no_duplicates option to exclude duplicated nets. 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. |

Example Usage |
