US 2022/0067262 A1 · AUTOMATION FOR MONOLITHIC 3D DEVICES

Abstract

A method of designing a 3D Integrated Circuit, the method including: performing partitioning to at least a logic strata, the logic strata including logic, and to a memory strata, the memory strata including memory; then performing a first placement of the memory strata using a 2D placer executed by a computer, where the 2D placer is a Computer Aided Design (CAD) tool for two-dimensional devices, where the 3D Integrated Circuit includes a plurality of connections between the logic strata and the memory strata; and performing a second placement of the logic strata based on the first placement, where the memory includes a first memory array, where the logic includes a first logic circuit controlling the first memory array, where the first placement includes placement of the first memory array, where the second placement includes placement of the first logic circuit based on the placement of the first memory array.
