Fast and Accurate Simulation Technique for Large Irregular Arrays

Fast and accurate jitter simulation technique for continuous-time SDmodulators

A fast and accurate technique for modelling and simulation of clock jitter in continuous-time sigma-delta (SD) modulators is introduced. In addition to its high speed compared to the traditional jitter simulation method, the proposed technique is still continuous-time based, which is more convenient than discrete-time based jitter modelling suggested in other publications. The mathematical prin...

Fast and Accurate Simulation

Yehea I. Ismail Department of Electrical and Computer Engineering Northwestern University Evanston, IL. 60208 Abstract A method is introduced to evaluate time domain signals witbin RLC trees with arbitrary accuracy in response to any input signal. This method depends on finding a low frequency reduced order transfer function by direct truncation of the exact transfer function at Merent nodes of...

Fast and Accurate Simulation of Gravitational Field of Irregular-shaped Bodies using Polydisperse Sphere Packings

Currently, interest in space missions to small bodies (e.g., asteroids) is increasing, both scientifically and commercially. One of the important aspects of these missions is to test the navigation, guidance, and control algorithms. The most cost and time efficient way to do this is to simulate the missions in virtual testbeds. To do so, a physically-based simulation of the small bodies’ physic...

A Novel Synchronization Technique for Fast and Accurate Multi-core Instruction-set Simulation

This paper proposes a synchronization technique for fast and accurate Multi-Core Instruction-Set Simulation (MCISS). Traditionally, a lock-step approach, which synchronizes every cycle, is commonly used to achieve accurate simulation results of MCISS. However, this approach results in immense overhead and low simulation speed. Rather than synchronizing every cycle, our approach synchronizes the...
