To run Pegasus Interactive, you must first have a snapshot. A snapshot is a collection of reference files that Pegasus Interactive refers during DRC. For details of these files, refer to All About Design Rules: Snapshot. For snapshot creation, Pegasus checks for the existence of license Pegasus_int during snapshot file creation, and allows the operation if that licenses exists.
During the snapshot creation, license requirement(s) is documented as a part of the snapshot header information. At this stage, no license is checked out and Pegasus Interactive only determines license requirement based on the content of rule deck.
Following figure illustrates test snapshot header information. It indicates that Pegasus_Int license is required for Pegasus Interactive to run successfully.
