1.The strong or weak level of link between subsystems is expressed through operation. The comprehensive effect degree of every subsystem(Effect Degree or Cause Degree) and its position and effect in Evaluation Target System(Centre Degree) is analyzed by DEMATEL method.
7.The new algorithm is applied to find the target location of cell during the placement optimization, and it is combined with a heuristic local optimization approach to experiment on MCNC (Microelectronics Centre of North-Carolina) standard cell benchmarks.
