Create Cellview Dialog Box – Replace or Modify

Replace does the following to a cellview:

■Discards any modifications you may have made to that cellview

■Creates only the pins, properties, selection box, labels, and other graphics; all schematic instances, schematic wires, and HDL body text are lost

■May alter the position of pins in the new symbol cellview

Modify does the following to a symbol cellview:

■Automatically edits the cellview with a minimal amount of changes to the current pin locations, graphics, and properties within the symbol cellview

■Deletes pins that are no longer needed

■Adds pins that do not yet exist in the new cellview

Pins are added near the bottom of the cellview. Use the symbol editor to reposition these new pins and to adjust any symbol graphics. The system determines attributes of the new pins by the currently active TSG template file.

■Adds or updates cellview properties and terminal properties

■Annotates the changes that were made in note format at the bottom of the cellview and in the Command Interpreter Window (CIW)

■Does not delete cellview or terminal properties
