In this paper we present an architecture of a via-configurable regular fabric. The basic logic block is composed of via-configurable functional cells placed in a circular fashion along with a via-decomposable flip-flop. Segmented, prefabricated wires provide the intra-block and inter-block connections. All the interconnects can be customized using a set of programmable via masks. This architecture can achieve performance similar to that of standard-cell-based designs in a comparable area, but with greatly reduced mask cost.
