Tcl Package and Version

Belongs to ::quartus::sdc_ext 1.0

Syntax get_registers [-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 register 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)
Returns a collection of registers in the design.

The default matching scheme returns not only registers
whose names match the specified filter, but also
returns registers duplicated from these registers
(cells automatically generated from these registers by
the Quartus Prime software). Use the -no_duplicates
option to exclude duplicated registers.

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.

Avoid using the get_registers command if your design
targets a HardCopy series device or if you plan to
migrate your design to a HardCopy series device.
Example Usage
