COMPUTER-IMPLEMENTED METHOD, PROCESSOR-IMPLEMENTED SYSTEM, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM STORING INSTRUCTIONS FOR SIMULATION OF PRINTED CIRCUIT BOARD

摘要

A computer-implemented method for a simulation of a printed circuit board includes dividing a layout of the printed circuit board into elements having the same size, detecting first elements that have at least two materials from the elements, calculating anisotropic attributes of the first elements and assigning the anisotropic attributes to each of the first elements, and calculating a warpage of the printed circuit board based on the anisotropic attributes of the first elements. The anisotropic attributes depend on physical properties according to directions of the first elements on the layout.
