An approach for multilevel logic cell optimization in module generators

The authors present new ideas in the field of multilevel optimization for automatic logic macrocell synthesis. The proposed new approach performs a quasi parallel optimization of very different and complex tasks via a simulated annealing based expert system. A true design space exploration is achieved, 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. A small prototype software system had been implemented and it is shown how this new approach, e.g. can be used within a module generator.<>
