collection Definition

A custom group of targets (that is, a group of named cells, clocks, nets, nodes, pins, ports, or registers) in your design to which you can assign timing constraints and obtain timing data with the Timing Analyzer. You can define the criteria of a collection in the Name Finder dialog box or with the command-line interface using the following commands and names:

  • The get_cells, get_clocks, get_keepers, get_nets, get_nodes, get_pins, get_ports, or get_registers SDC commands
  • Partial node names
  • Wildcards
