What is logic synthesis?
Logic Synthesis Logic Synthesis • Generates a logic circuit from various kinds of descriptions such as truth table, Boolean expression, etc. • Important metrics:area (#gates) and depth (#levels) Two-Level Logic
What is a logic synthesis and verification paradigm based on circuit simulation?
Abstract—This paper proposes a new logic synthesis and veri- fication paradigm based on circuit simulation. In this paradigm, high-quality, expressive simulation patterns are pre-generated to be reused in multiple runs of optimization and verification algorithms, resulting in reduced time-consuming Boolean com- putations such as SAT-solving.

What is simulation-guided resubstitution in logic synthesis?
SIMULATION-GUIDED RESUBSTITUTION In this section, the simulation-guided paradigm is demon- strated with Boolean resubstitution as an example application in logic synthesis. The main difference of our algorithm, compared to a state-of-the-art resubstitution algorithm , 0. is in the representation of the divisors.

the ABC is composed of logic synthesis, technology mapping, and verification. Because of the variety of technology and the more "black box" nature, the logic synthesis community has focused on the logic synthesis algorithm alone. In other words, the literature often targets to optimize the statistic of the logic graph, such as the

A logic synthesis algorithm, Boolean resubstitution, and a verification algorithm, combinational equivalence checking, are two examples of using this paradigm. In simulation-guided Boolean resubstitution, simulation patterns are used for efficient filtering of optimization choices, leading to a lower cost in expanding the search space.

Abstract—Logic synthesis is a fundamental step in hard- ware design whose goal is to find structural representations of Boolean functions while minimizing delay and area. If the function is completely-specified, the implementa- tion accurately represents the function.
