A reformulation of the Transmission Line Matrix (TLM) method is presented to model non-dispersive anisotropic media. Two TLM-based solutions solve this problem can already be found in literature, each one with an interesting feature. One considered a more conceptual approach, close TLM fundamentals, which identifies Maxwell’s equations specific line. But simplicity achieved at expense increase ...

This paper describes a new subgridding approach with a view to improving the efficiency of full-wave simulation of electronic circuits. The proposed subgridding method has been incorporated into a full-wave variable-mesh finite-difference transmission line matrix (FD-TLM) simulator. By incorporating the proposed subgridding method, a speed-up of about 2 has been attained. The computational acce...

The increasing interest in metamaterials with negative refractive index has been prompted by a variety of promising optical and microwave applications. Often, the resulting electromagnetic problems to be solve are not analytically derivable; therefore, numerical modeling must be employed and the Transmission Line Modeling (TLM) method constitutes a possible choice. After having greatly simplifi...

One of the main critical tasks in a design flow based on Transaction Level Modeling (TLM) is the implementation of transactors. In fact, even if transactors represent the key objects to allow TLM-RTL mixed simulation, testbench and assertion reuse, their implementation is still manual, tedious and errorprone. The paper firstly classifies two scenarios as starting points to generate transactors ...

The transmission-line modelling (TLM) method has been widely applied to many areas including electromagnetic and heat conduction problems. Its unstructured version, TLM (UTLM), however, not hitherto fully exploited in thermal diffusion This paper derives detail a UTLM scheme solve the two-dimensional equation numerically based on optimal Delaunay triangular (ODT) mesh.

This paper compares ray tracing, finite difference time domain, and the event driven transmission line matrix models as tools for making site specific pathloss predictions in cluttered environments. A brief overview of each type of model is presented. The accuracy and computational cost of a ray tracing, FDTD, and event based TLM model are compared for a small, indoor propagation experiment. Th...

In this paper we propose a fault-tolerant architecture for mesh-based network on chips to recover from permanent faults in switches. We add a number of spare links between processing elements and their neighboring switches and some logic redundancy to network elements. Also online fault detection and correction strategies are presented for this architecture. We model and simulate the communicat...
