To date, the probabilistic approach is in widespread use to analyze the power dissipation of digital circuits. The goal of the present work is twofold. First, b present a method in providing an evaluation package of signals' probabilities and transition densities that can he applied at different specification levels with more 01' less accuracy. A first(More)
1 In deep submicron technologies, the verification task has to cover some new issues to certify the correctness of a design. The noise produced by crosstalk couplings is one of these emerging problems. In this paper, we propose a model to evaluate the peak value of the noise injected on a signal when its neighboring signals make their transitions. This(More)

Among other threats, secure components are subjected to physical attacks whose aim is to recover the secret information they store. Most of the work carried out to protect these components generally consists in developing protections (or countermeasures) taken one by one. But this “countermeasure-centered” approach drastically decreases the performance of(More)
In very deep submicron technologies, the parasitic capacitor and resistance can have a significant impact on propagation delay and functional failure. Several methods consist in evaluating the output delay or giving an approximation of the output signal. These methods are really simple and are easily used in timing analysis. However, they are unusable in(More)
Crosstalk noise is due to the effect of the transition of a signal-called aggressor-on its neighbours-called victims. A lot of analytical methods propose to evaluate crosstalk noise without taking into account the fact that all the neighbour signals are not making a transition in the same time. Thus, the crosstalk noise is overestimated. We propose a novel(More)
Distributed simulation represents an attractive and smart way of improving the verification speed of large VLSI circuits. Unfortunately, this inexpensive approach suffers from the low performance of the communication networks used to connect local workstations. In this paper, we present a partitioning algorithm that attempt to find a suitable balance(More)
