Enhancing power distribution system through 3D integrated models, optimized designs, and switching VRM model

After conducting 3D integrated modeling of an Intel microprocessor, a distributed load current model represented the non-uniform power distribution on the chip is hooked up the on-chip interconnect. The on-chip interconnect is then tied to the integrated model. A multiple-phase, full synchronous switched dc/dc converter model is connected to the other end of the integrated model. Performance evaluation of the complete power delivery system based on a single and multiphase dc/dc converter is made. Advantages and disadvantages of each design are noted. Differences in the output characteristics with a simple source replacement of the dc source and with an actual voltage regulator module are highlighted.
