Design and Implementation of Memory-less Forbidden Transition Free Crosstalk Avoidance CODECs for On-Chip Buses
Recently, reducing crosstalk noise delay is an important issue in VLSI design. As circuit geometries become smaller, wire interconnections become closer together and taller, thus increasing the cross-coupling capacitance between nets. At the same time, parasitic capacitance to the substrate becomes less as interconnections become narrower, and cell delays are reduced as transistors become smaller. In this work, we present a CODEC design for the forbidden transition free crosstalk avoidance CODEC. Our mapping and coding scheme is based on the Binary number system. In this paper, we investigate and propose a bus forbidden transition free CODECs for reducing bus delay and our experimental results show that the proposed CODEC complexity is orders of magnitude better compared to the existing techniques. Compared to the best existing approaches, we achieved a 3 times faster design and improvement in logic complexity.
