### Abstract

This paper proposes a fast depth-constrained technology mapping algorithm for logic-blocks composed of tree-structured lookup tables. First, we propose a technology mapping algorithm which minimizes the number of logic-blocks if an input Boolean network is a tree. Second, we propose a technology mapping algorithm which minimizes logic depth for any input Boolean network. Finally, we combine those two technology mapping algorithms and propose an algorithm which realizes technology mapping whose depth is bounded by a given upper bound d _{c}. Experimental results demonstrate the effectiveness and efficiency of the proposed algorithm.
