The design process of digital circuits is often carried out in individual steps, like logic minimization, mapping and routing. This leads to quality loss e.g., in cases where highly optimized netlists fit badly onto the target architecture. Lattice diagrams have been proposed as one possible solution. They offer a regular two dimensional structure, thus overcoming the routing problem. However elegant, presented methods have only shown to find practical lattice representations for small functions. We present heuristic synthesis methods for Pseudo-Symmetric Pseudo Kronecker Decision Diagrams (PSPKDDs) applicable to incompletely specified multiple output functions. The lattice structure maps directly to both ASICs and fine grain FPGAs. Our method (combining logic minimization, mapping and routing) seeks to minimize area and delay by heuristic methods. Experimental results on a set of MCNC benchmarks show superior quality to previous methods and in many cases even optimal depth results for unfolded lattices.
