Feasibility study of transmission between wireless interconnects in multichip multicore systems

The paper presents a feasibility study of transmission between wireless interconnects in Multichip Multicore (MCMC) systems. The MCMC model consists of four IC's, each with four cores that are placed at the corners. For this work, 4 electrically small monopole antennas are considered as wireless interconnects, placed on 3 IC's. Simulation is performed using ANSYS Electronics suite. As expected, transmission decreases with the distance between the antennas. Further, distortions of the radiation pattern due to the lossy silicon layer and the ground plane, significantly affect the transmission between the antennas. For experimental validation, zigzag antennas have been fabricated on silicon wafers. Measurements and analysis for a wireless channel modeling is under progress.
