Verify Design Mode
This Pegasus Interactive mode is an area specific and on-demand DRC. You can specify initial area of checking ranged from the whole cellview to one changed portion of the layout. There are three initial area of checking modes available:
Both Current CellView and Visible Area are static DRC while Changed Area is a dynamic DRC. By definition, a static DRC is run on polygons within the area of interest as it-is. On the contrary, dynamic DRC checks only on the modified portion of layout, which is tracked by Pegasus Interactive. Any editing done from the moment layout is opened prior to DRC is considered as the modified portion of the layout. This layout editing tracking is stored temporarily in the virtual memory and is reset after Pegasus Interactive completes DRC.
Regardless the hierarchy depth displayed in the layout, Pegasus Interactive checks on all polygons found within the area of checking.
In general, you can interactively set area checking mode for a given window and this is a Virtuoso session based setting. Furthermore, you can control the default Verify Design mode area setting through PegasusInt_InitArea.
