Abstract
A method implemented as a computer program product for comparing two designs of electronic circuits, wherein the design representations comprise several hierarchically related sheets. The method comprises the steps of (a) identifying corresponding top-sheets of the first hierarchy level in the design versions; (b) generating a list of all sub-sheets for each top-sheet and comparing the lists to identify added, removed and common sheets of the corresponding top-sheets; (c) defining the common sheets as corresponding top-sheets of a next hierarchy level; and (d) repeating steps (a)-(c) until at least one of the top-sheets does not comprise any sub-sheet.
