Generalizations of Rent's rule

This paper describes some new results with respect to the classic problem of the component-to-pin ratio. Generalizations of Rent's rule, providing greater accuracy and extending the domain of applicability are presented. The two weaknesses of Rent's rule-the limited range on the number of components in a block and on the Rent exponent-are eliminated. The resulting generalized rules are based on parameters that can be measured from actual designs. The new rules have been found to produce very satisfactory results on test and industrial circuits.<
