Abstract: Provided are a method and system for visualization of a 3D electronic device. The method includes: a structural and/or electrical characteristic of the electronic device is simulated to obtain first visualization data, the electronic device including a semiconductor device and/or an integrated circuit and the first visualization data including 3D grid position information of the electronic device and/or a physical quantity at a grid point; the 3D grid position information and/or physical quantity at the grid point in the first visualization data are/is converted into second visualization data suitable for virtual 3D displaying according to a data type; and the second visualization data is rendered in a virtual space to display a structure and/or physical quantity of the electronic device in the virtual space.
