System and method for designing semiconductor package using computing system, apparatus for fabricating semiconductor package including the system, and semiconductor package designed by the method

A system for designing a semiconductor package using a computing system, comprising: a virtual stacking module configured to receive a layout parameter for a first chip, a layout parameter for a second chip, and a layout parameter for a package substrate, and in response to the layout parameters of the first chip, the second chip, and the package substrate, generate a plurality of virtual layouts in which the first and second chips are stacked, on the package substrate; a modeling module configured to model operating parameters for the first and second chips and the package substrate in response to the virtual layouts; and a characteristic analyzing module configured to analyze operating characteristics of the virtual layouts in response to the modeled operating parameters.
