By analyzing the working characteristics of binary Schmitt circuits we find their sequential characteristics, which makes us follow the method of sequential circuits to design Schmitt circuits. The sequential design technique is extended to the study of ternary Schmitt circuits in this paper. The designed ternary Schmitt trigger has a similar structure with a ternary flip-flop. PSPICE simulatio...

Testing of Sequential circuits can be done by two test vectors (all 1’s and all 0’s) if the circuits were based on the conservative logic. The circuit is made to be tested by designing the circuit with the help of Reversible logic gates. Toffoli gate is used as reversible gate in this paper. Sequential circuits such as latches, flip flops are designed with the help of conservative logic reversi...

Implicit reachable state computation can be applied to a wide range of sequential formal veriication and logic synthesis problems. Symbolic manipulation with BDDs is one of the most eecient techniques known for the reachability analysis. The technique was rst proposed by Coudert et al. in 1989, and was improved later by Touati et al. in 1990. The standard approach chooses the cut of a sequentia...

A fundamental feature of Dynamically Recon gurable FPGAs (DRFPGAs) is that the logic and interconnect is timemultiplexed. Thus for a circuit to be implemented on a DRFPGA, it needs to be partitioned such that each subcircuit can be executed at a di erent time. In this paper, the partitioning of sequential circuits for execution on a DRFPGA is studied. To determine how to correctly partition a s...

Modern circuit implementation technologies (FPGAs, CPLDs and complex gates) invalidate the traditional sequential synthesis methods. The new implementation platforms introduce new optimization criteria and implementation constraints the circuit optimization cannot be identified with the minimization of the number of terms or literals. It is necessary to perform the logic synthesis according to ...

We constructed an analog circuit generating fluctuations of which a probability density function has power law tails. In the circuit fluctuations with an arbitrary exponent of the power law can be obtained by tuning the resistance. A theory of a differential equation with both multiplicative and additive noises which describes the circuit is introduced. The circuit is composed of a noise genera...

Verification and Synthesis of Clock-Gated Circuits by Yu-Yun Dai Doctor of Philosophy in Engineering-Electrical Engineering and Computer Sciences University of California, Berkeley Professor Robert K. Brayton, Chair As system complexity and transistor density increase, the power consumed by digital integrated circuits has become a critical constraint for VLSI design and manufacturing. To reduce...

Abstract TRIVIUM is the simplest ECRYPT Stream Cipher project Candidate which deals with key and IV of length 80. Using the sequential Circuit Approximation method, introduced by Golic in 94, we derive a linear function of consecutive keystream bits which is hold with correlation coefficient of about 2. This shows that TRIVIUM is strong against linear sequential circuit approximation attack in ...

With increasing sizes of designs and the need for low power applications, power is another optimization constraint that has become critical in addition to timing and area for electronic circuits. The work presented in this paper exploits a fundamental and important source of power reduction – shutting down useless parts of a sequential circuit. This idea is known as power management. In our app...
