Connectivity-Driven Layout Editing Commands Supported by DPA
For optimal planning of virtual hierarchies in a layout design, Design Planning and Analysis (DPA) supports several Virtuoso Layout Suite commands.

Generate All From Source
|
Generate layout counterparts for soft and hard blocks.
For schematic instances that have no layout representations available, generate a virtual hierarchy with a selectable area boundary that is snapped to the width spacing patterns (WSP) grid.
Generate soft blocks for schematic components that are missing. Use the Snap Pattern Snapping option on the Layout Editor Options form to control snapping of the generated objects.

Generate Selected From Source
|
Generate a virtual hierarchy for the selected schematic instances that have no layout representations.
The generated virtual hierarchy has a selectable area boundary that is snapped to the width spacing patterns (WSP) grid. Use the Snap Pattern Snapping option on the Layout Editor Options form to control the snapping.

Edit In Place
|
Edit in place the generated virtual hierarchy clones.
To edit the virtual hierarchies that are not clone instances, adjust the display depth to make them transparent.

Check Against Source
|
Check and report mismatches in connectivity, instance terminal mismatches, and so on, between the schematic and layout views for the virtual hierarchies selected at the top level or for the ones available on Edit In Place.

Update Components And Nets
|
Update the components from source and if the selected set that has missing instances contains a virtual hierarchy group, generate the missing components inside the virtual hierarchy group. In addition, preserve the area boundary of the instances inside the virtual hierarchy group and generate soft blocks for schematic components that are missing.
