| Syntax | get_nodes [-h | -help] [-long_help] [-include_generated_clocks] [-no_duplicates] [-nocase] [-nowarn] [-of_clocks] [ <filter> ] | |||
| Arguments | -h | -help | Short help | ||
| -long_help | Long help with examples and possible return values | |||
| -include_generated_clocks | Includes generated clocks derived from the matched clocks. This option can only be used in conjunction with the -of_clocks option. | |||
| -no_duplicates | Do not match duplicated node names | |||
| -nocase | Specifies the matching of node names (or clock names if the -of_clocks option is used) to be case-insensitive | |||
| -nowarn | Do not issue warning messages about unmatched patterns | |||
| -of_clocks | Returns nodes that are on the clock domains of the specified clock names | |||
| <filter> | Valid destinations (string patterns are matched using Tcl string matching) | |||
| Description |
Returns a collection of nodes in the design. The default matching scheme returns not only nodes whose names match the specified filter, but also nodes duplicated from these nodes (refers to cells are automatically generated by Quartus from these nodes). Use the -no_duplicates option to not include duplicated nodes. If the -of_clocks option is used, the nodes returned are limited to those on the clock domains of clocks whose names match the specified filter. 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. |
