Update Connectivity Reference Form

Use the Update Connectivity Reference form to update the source for your layout view and to change the physical configuration which specifies how the layout is generated from the source.

Field

Description

Source View Definition

This section lets you specify the view to use as the connectivity source

Use schematic view

Specifies Layout XL to use a schematic view as the connectivity reference. If you uncheck the box, it means there is no connectivity reference.To specify the schematic to use, do one of the following.

  • Type the Library, Cell, and View names of the schematic in the fields provided. You can type in the name of a different library. The default view name is schematic.
  • Use Sel by Cursor and click an open schematic window.
  • Use the Browse button to browse your file system for the schematic you want.

Update layout cellviews hierarchically

Descends into a hierarchical layout cellview and updates the library setting for any lower-level cellviews in accordance with the library name specified for the top-level cell, except:

  • Where the lower-level cellview is a leaf (i.e., there is no instance in the cellview).
  • The current setting points to a non-existent cellview.Lower-level cellviews updated in this way are not saved until you confirm that you want to do so at the end of the session.

Physical Configuration View Definition

This section lets you specify definitions for physical configuration view.

Use configuration view

Lets you specify the physical configuration view to use for the schematic-layout pair. If you deselect this check box, Layout XL runs without a physical configuration.To specify a physical configuration to use, do one of the following:

  • Type the Library, Cell, and View names of the view in the fields provided. You can type in the name of a different library. The default view name is physConfig.
  • Use the Browse button to browse your file system for the view you want.

Environment variables: cphUseLayoutLibrary, cphUseLayoutViewName

Stop Level

Specifies the stop level for elaboration of the logical design hierarchy. Once saved in the layout, the specified stop level value remains unchanged until the value is manually updated. The value set here takes precedence over the one set in CPH or using the environment variable.

Environment variable: cphStopLevel
