Novel Zero Crosstalk Encoding/decoding techniques for SOC

Today´s high density fabrications on chip have resulted in closer interconnects. As a downside, external radiation, crosstalk coupling, supply voltage fluctuations, temperature variations, electromagnetic interference (EMI) or combinations of these manufacturing defects have increased. Of these the major concern is that of crosstalk and its consequences. In the past, multiple techniques such as shielding, use of repeaters and guard rings were proposed to alleviate the undesired signal transitions. These bygone techniques where debunked since implementing them resulted in additional wires which increases routing area. These shortcomings laid the path towards innovative encoding schemes like the No Adjacent Transitions (NAT), Boundary Shift Coding (BSC) and Bus invert technique etc. This paper proposes a novel Zero Crosstalk Encoding Scheme and explores its potential applications to alleviate the concerns of crosstalk in decisive communication modules. The Zero Crosstalk Scheme generates codes which results in a 100% reduction in unenviable signaling transitions for Type-3 and Type-4 crosstalk.
