Manipulate Sets

---

A set is a collection of design objects. Sets can be selected and highlighted. You can have only one selected set for a cellview but can have many highlight sets. When you interactively select objects in a cellview window, you are adding objects to the selected set. Similarly, in highlight mode, you add and remove objects from highlight sets.

When a set is created, it is uniquely identified by a set identifier. You can save the set identifier in a Tcl variable and use the variable as an argument for the set commands.

Following is a list of Tcl commands that are used for basic set functions.

• and_sets
• clear_set
• copy_set
• not_sets
• or_sets
• replace_set
• xor_sets
