Guest Editorial Introduction to the Special Issue on Modeling and Simulation of Mixed and Analog-Digital Systems

Integrated circuit technology is perhaps one of the fastest growing technology sectors, with rapid progress being made in the design and fabrication processes. The design of more complex and increasingly dense designs continues at a frantic pace. Rapid scaling of device sizes now enables complete systems to be integrated on chip. The newer generations of integrated circuits are no longer purely analog or digital but include a combination of different functionalities. Mixed signal system design that largely combine analog and digital sections has also evolved into a field of its own to keep pace with this technology trend. We devote this special issue to report on the leading-edge enabling developments in the modeling and simulation area, necessary to support and fuel the mixed-signal design trend. In this issue we have collected an excellent representative set of papers that covers different aspects of this area.
