The Impact of Information Flow Control on FCN Circuit Design

Following the continuous advancement of CMOS technology, propelled by transistor miniaturization and Moore's Law, the scientific community is currently exploring emerging paradigms to discover novel approaches for developing computational systems. One of the emerging alternatives is Field-Coupled Nanocomputing FCN, which, unlike conventional CMOS, doesn't rely on electric current as the state variable for encoding information. Instead, logic is dictated by the coupling of near fields. This paper presents critical concepts for understanding how information flow control is a crucial aspect in the design of Field-Coupled Nanocomputing circuits. We have reviewed the leading alternatives for FCN implementation, examining how each executes information control and how this ultimately impacts EDA tools.
