This gaper presents a parallel pattern compiled code logic simulator which can handle the transport delay as well as the inertial delay of the logic gate. It uses Potential-Change Frame, incorporating with inertial functions, to execute event-canceling operation for gates, thus eliminating the conventional time wheel mechanism. As a result, it can adopt the parallel pattern strategy to increase the simulation speed. Furthermore, it is a compiled code simulator, which further improves its performance. Experimental results show that it surpasses significantly over the conventional time wheel. event-driven simulator in the simulation speed. In addition, it is also found that, significant percentage (27%) of hazards should be eliminated when only the transport delay is considered in the simulation.

We develop an algorithm to identify invariant curves efficiently. In dynamical systems, it helps do continuations of branches of quasi-periodic solutions smoothly in bifurcation diagrams. Several examples are demonstrated to provide the numerical evidence for the versatility of the algorithm. (C) 2001 Elsevier Science B.V. All rights reserved.

In this paper, we perform our algorithm developed in [Yu & Lee, 2001] to present the entire branches of quasiperiodic solutions starting from the bifurcation points in the branches of periodic solutions in an interval of parameters for the 2-mode damped, driven sine-Gordon ODE.
