Abstract : an algorithm of minimizing the number of buffers under certain delay constraint with accurate delay models is presented. given a two - terminal net, the algorithm can minimize the total number of buffers inserted to meet the delay constraint. a high order delay model is applied to estimate interconnect delay and a nonlinear delay model based on look - up table is for buffer delay estimation. the experimental results show that the algorithm can efficiently achieve the trade - offs between number of buffers and delay, and avoid needless power and area cost. the running time is satisfactory
