Abstract
A repeater insertion method is described which allows for repeater cell insertion into two or more fanout nets. Repeater cell location is determined such that at any given point, the interval capacitance between any two repeater cell nodes is no greater than a predetermined amount. Furthermore, the method allows for successful “back-annotation” into synthesis or layout software without the need to add new input/output pins to the module definition. Additionally, the method allows for repeater cell insertion using two or more sizes of repeater cells. Finally, the method described considers the “slack” of each fanout, and makes the signal delay from the source to the most critical fanout shorter than the result of usual repeater insertion methods.
