Abstract :
An efficient algorithm for a logic synthesis system based on global dynamic extraction and flexible cost (GDEF) is described. The GDEF is designed to find the best common subexpression and to update the value of the other common subexpressions dynamically. The GDEF feedbacks approximate layout area obtained through an area-estimation program to guide the logic synthesis process. In this approach, the cost function is dependent on both literal count and estimated area
