An in-circuit diagnostic test structure triggered by a light pulse captures logic states on-chip with picosecond timing accuracy, and the results read out via a scan chain thus providing precise logic transition time information from deep inside the chip, greatly aiding failure analysis. The method could also make time measurement of switching events inside an IC when it is mounted in a printed...

Complex networks of dynamically connected saddle states persistently emerge in a broad range of high-dimensional systems and may reliably encode inputs as specific switching trajectories. Their computational capabilities, however, are far from being understood. Here, we analyze how symmetry-breaking inhomogeneities naturally induce predictable persistent switching dynamics across such networks....

This paper presents reviews and briefly discuss recent development in spectral methods in switching and multiple-valued logic theory and the design of digital systems.

In this work, switching systems are named endogenous when their switching pattern is controllable. Linear endogenous switching systems can be considered as a particular class of bilinear control systems. The key idea is that both types of systems are equivalent to polysystems i.e. to systems whose flow is piecewise smooth. The reachable set of a linear endogenous switching system can be studied...

We demonstrate how to configure and reconfigure a nanoelectronic nonlinear network to a universal set of logic gates by applying sequences of voltage pulses to the edges of the network. The nanoelectronic device is designed to consist of a self-assembled network of nanoparticles connected by two-terminal linker elements with hysteretic behaviour, allowing voltage-controlled switching between a ...

This paper reports design of a ring oscillator using CS-COMS low noise logic family for mixed signal SOCs. Design has been implemented using 180nm technology with 1.8V supply voltage using CSCMOS logic. CS-CMOS logic efficiently reduce switching noise while maintaining the speed as compare to the other logics like CSL, CBL etc. After completion of the design authors have simulated the design in...

We propose a logic synthesis system that includes power optimization after technology mapping. Our approach is unique in that our post-mapping logic transformations take into account information on circuit delay, capacitance, arrival times, glitches, etc, to provide much better accuracy than previously proposed technology-independent power optimization methods. By changing connections in a mapp...

New design methods and tools are needed to improve the process of designing dynamically reconfigurable logic. This paper reports on the revision and extension of Dynamic Circuit Switching (DCS), a CAD tool for specifying and simulating dynamically reconfigurable systems. The work introduces a new design framework, which exploits existing design practices where feasible, and proposes a new desig...

All-optical 2R logic regeneration is demonstrated using a vertical cavity semiconductor optical amplifier. The optical switching threshold is 1 μW, with 10 dB gain and >6:1 (8dB) extinction ratio. Performance limits are also discussed. ©2003 Optical Society of America OCIS codes: (190.1450) Bistability; (200.4660) Optical Logic; (250.5980) Semiconductor Optical Amplifiers; (230.4320) Nonlinear ...

Electronic systems became an essential component of our lives. The demand for increased functionality is satisfied by higher integration which, however, make the design process more complex and introduces new problems. These problems must be considered in every step involved in the design of electronic systems. One of these steps is verification checking, whether what is manufactured will work ...
