In this paper, we describe a new via-configurable routing architecture which shows much better throughput and performance than the previous structures. We demonstrate how to construct a single-via-mask fabric to reduce further the mask cost, and we analyze the penalties which it incurs. To solve the routability problem commonly existing in fabric-based designs, an efficient white-space allocation scheme is suggested, which provides a fast design convergence and early prediction of the circuit mappability to a given fabric.
