Abstract
A technology mapping method and device for mapping cost functions on directed acyclic graphs, using decoupled matching and covering and circumventing the memory explosion usually caused by this decoupling. Multiple matches are generated at the head of a wavefront process and embedded within the network. Covering is done at the tail of the wavefront to optimize one or more cost functions.
