A new approach for multilevel logic cell optimization

Presents new ideas in the field of multi-level logic optimization for automatic logic macrocell synthesis. A new approach is proposed which performs a quasi-parallel optimization of very different and complex tasks via a simulated annealing based expert system. A first working prototype software package for multilevel logic cell optimization had been implemented to prove the validity of this approach. The system performs a real architecture exploration, finding the best solution with respect to a certain cost-function which takes into account actual design parameters like speed, area, power, and not only indirect parameters like number of literals etc. Another feature is the small and primitive set of required rules
