“…Using the data from [9], we have performed a simulation based timing analysis [10,11,12] in VHDL by Aldecs Active-HDL. In this analysis, a suitable extension of the logic simulation process enables all the worst case delays for all the paths in one digital circuit to be obtained with only one run of the simulator.…”

In modern computing technique, calculation of leading zeros in a data represented as strings of digits is used very often. Those techniques require high speed of the circuit, as well as its fast design. In this paper we propose a design of such a counter, which is applicable to data length of w = 4j bits, for 4 < j ≤ 8 . With this solution it is also possible to process longer data, since the suggested technique offers a good modularity. This is very important, considering the current technology scaling trends. In this paper, a delay behavior of the proposed circuit has also been investigated using equations and VHDL simulation based worst-case delay estimation method. The results show a significant improvement of the circuit speed, compared to the known solutions.

“…That is, determining the delays of the paths in a particular asynchronous circuit. Early evaluation of the path delays in the circuit helps avoiding early timing problems as well as circuit performance characterization (Sokolovic, Litovski & Zwolinski 2009). Precise paths delays, of course, can be estimated only in the final steps of the design process.…”

and 2005, respectively. He held industrial research positions with Panasonic in Japan and 3M in USA, conducting R&D of micro devices and fabrication technologies for over ten years. Presently, he is an Assistant Professor at the University of British Columbia, Canada, as well as a Canada Research Chair. Prof. Takahata has published many papers and holds several issued patents in MEMS and micro/nanofabrication. He has served on committees for international conferences such as the IEEE MEMS and the IEEE Transducers. He also served as the editor of an InTech book Micro Electronic and Mechanical Systems. His research interests are in the areas of MEMS, nanotechnology, and micro/nanomanufacturing, including wireless microdevices, bioMEMS, nanomaterials and microstructures integration, and microplasma control and application. PrefaceThe miniaturization and performance improvement in semiconductor devices and integrated circuits (ICs) are expected to continue through leveraging of nanotechnologies and nanomaterials. This evolution should accelerate the System-on-a-Chip (SoC) trend, i.e., singlechip integration of multifunctional, mixed-signal electronic components, toward realizing embedded nanoelectronic systems. In parallel with advances in electronics, we are witnessing the rise of micro-electro-mechanical systems (MEMS), with rapidly growing commercial opportunities and markets extending to a broader range of industrial sectors on a global scale.The emergence of MEMS is primarily attributed to the establishment of sophisticated IC manufacturing techniques and processes that served as a foundation for realizing many innovative silicon-based micromachining technologies. Advances in this area have brought about a revolution in mechanical engineering, enabling the miniaturization and system-level integration of mechanical structures and devices with ICs on a chip for MEMS fabrication. With miniaturized sensors and actuators, MEMS provide us with the ability to interact with micro-scale environments with non-electrical/-electronic parameters, found in the mechanical, optical, chemical, biological, and other domains. This exceptional ability has led to their application in fields ranging from implantable medical sensors to video game controllers. There is no doubt that continued development of MEMS and microsystems with electromechanical functionalities will extend their contribution to society, in parallel with the evolution of IC technologies.This book discusses key aspects of these technology areas, organized in twenty-seven chapters that present the latest research developments in micro electronic and mechanical systems. The book addresses a wide range of fundamental and practical issues related to MEMS, advanced metal-oxide-semiconductor (MOS) and complementary MOS (CMOS) devices, SoC technology, integrated circuit testing and verification, and other important topics in the field. Several chapters cover state-of-the-art microfabrication techniques and materials as enabling technologies for the microsystems. Reliabili...
