Multiple-valued logic minimization using universal literals and cost tables

We propose a minimization algorithm that combines cost tables and simulated annealing. Unlike other minimization procedures that use cost tables, our method does not rely on the enumeration of all minterms, it works directly with the expression (a sum of product terms). We tested our method with a cost table obtained from current mode CMOS. The algorithm can be readily adapted to any other technology by simply replacing the cost table. The technology dependency is limited to the cost table. Results from our implementation are very encouraging.
