A method and computer program product for verifying an incremental change
to an integrated circuit design include receiving as input an integrated
circuit design database and an engineering change order. Objects in the
integrated circuit design database are identified and marked to indicate
a current state of the integrated circuit design database. The
engineering change order is applied to the integrated circuit design
database, and the integrated circuit design database is analyzed to
generate a list of incremental changes to the integrated circuit design
database resulting from the engineering change order. Objects in the
integrated circuit design database included in the list of incremental
changes are identified and marked to distinguish objects in the
integrated circuit design database that were changed from the current
state. The marked integrated circuit design database distinguishing the
objects that were changed from the current state is generated as output.
