Abstract :
Logic synthesis has two stages of optimization: technology-independent and technology-dependent. This paper surveys state-of-the-art methods for estimation and optimization of delays of logic circuits at the technology-independent stage. Although at this stage we cannot completely predict final delays after technology mapping, there exist reasonably accurate estimation techniques. Final delays can be reduced with optimization techniques that use such estimation
