Methods of designing a 3D Integrated Circuit including: partitioning at least one design into at least two levels, a first level and a second level, where the first level includes first transistors, where the second level includes second transistors is on top of the first level; providing placement data of the second level; performing a placement of the first level using a placer program executed by a computer, where the placement of the first level is based on the placement data, where the placer is part of a Computer Aided Design (CAD) tool, and where the first level includes first routing layers; performing a routing of the first level using a router {part of the CAD tool or another CAD tool) executed by a computer, where at least one metal routing layer is disposed in-between the first transistors and the second transistors, and the second level includes repeating structures.

The application belongs to the technical field of three-dimensional CAD software testing, and specifically provides a three-dimensional CAD software testing method and system based on a unified test case script, wherein the method comprises the following steps: S1, starting an automatic testing function through a button or a menu, and realizing automatic testing by calling an entry function of the unified test case script through a C++ integrated Python interface; S2, calling a unified standard test API interface of three-dimensional CAD software by the unified test case script through a Python integrated C++ component interface technology; wherein each test case has an entry function, and the automatic testing function is completed; by running the same test case on different three-dimensional CAD software, the same model and performance data test results are output, and conditions are provided for the comparability test of each three-dimensional CAD software. The modeling process is automatically completed through one-key operation, and the process of drawing a figure / model by clicking and moving a mouse in a drawing area provided by three-dimensional CAD tools is omitted.
