SCAN CHAIN WIRELENGTH OPTIMIZATION USING Q-LEARNING BASED REINFORCEMENT LEARNING

Abstract:

A method, a computer system, and a computer program product for scan chain wirelength optimization is provided. Embodiments of the present invention may include obtaining root nodes details from the root nodes. Embodiments of the present invention may include optimizing a connectivity of the root nodes. Embodiments of the present invention may include identifying a best start node and a best end node for each of the root nodes. Embodiments of the present invention may include optimizing child nodes in each of the root nodes. Embodiments of the present invention may include determining that a wirelength of a full tour is shorter or longer than a nearest neighbor. Embodiments of the present invention may include applying or skipping a solution.
