Optimal technology mapping for single output cells
Uwe Hinsberger, R. Kolla · 2002
This paper presents a new approach to technology mapping for arbitrary technologies with single output cells. It overcomes the restrictions of tree-mapping based methods. Optimal algorithms for special cases of DAG-mapping are presented: for minimum delay mapping and for duplication-free mapping under a class of simple cost functions (including area and delay). Heuristics for duplication of logic and for AT-tradeoffs are developed and applied to LUT-FPGAs.
