get_nodes

Usage

get_nodes [-no_duplicates] [-nocase] [-nowarn] <filter>

Options

-no_duplicates: Do not match duplicated node names

-nocase: Specifies the matching of node names to be case-insensitive

-nowarn: Do not issue warnings messages about unmatched patterns

<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.

The filter for the collection is a Tcl list of wildcards, and must follow standard Tcl or TimeQuest-extension

substitution rules. See help for the use_timequest_style_escaping command for details.

Example

project_open chiptrip

create_timimg_netlist

set nodes [get_nodes *name*]

foreach_in_collection node $nodes {

puts [get_object_info -name $node]

}

delete_timing_netlist

project_close
