ESIM is a simulation tool that integrates logic fault and design error simulation for logic circuits. It targets several design error and fault models, and uses a novel mix of simulation algorithms based on parallel-pattern evaluation, multiple error activation, single fault propagation, and critical path tracing. Several experiments are discussed to demonstrate the power of ESIM.

In this paper we propose a new algorithm for parallel enumeration of combinations. This algorithm uses N processing elements (or PEs). We prove that, if N and M are relatively prime, each PE will do the same operations and generate the same number of distinct combinations so that the computational load is well balanced. The algorithm has an important application in solving the problem of fault ...

Quantum and reversible logic circuits have more advantages than the common circuits, like low power consumption. These circuits are good choice to design future computers. One of the important issues in reversible logic is parity preservation. If parity of inputs and outputs are equal in reversible gate, this gate will be parity preserve. Reversible circuits made by these gates are parity prese...

Complex system recovery by process programming redundancy This paper presents the recovery of a control system resistant against faults. We come out from parallel computer system with distributed memory and communication based upon exchange of messages. This system consists of processor elements, communication lines and switches. At least one application process is running on each of the proces...

We examine the long-period near-source ground motions from simulations of M 7.4 events on a strike-slip fault using kinematic ruptures with rupture speeds that range from subshear speeds through intersonic speeds to supersonic speeds. The strong along-strike shear-wave directivity present in scenarios with subshear rupture speeds disappears in the scenarios with ruptures propagating faster than...
