This paper discusses the process of behavioral conversion of digital circuits used for signal processing applications into its neural network counterpart. The neural network so devised represents simulated digital circuits without any deviation in its input–output characteristics. However, the design of such networks depends entirely on different parameters and thus the design process too. It i...

This paper shows how digital logic may be taught to undergraduate students through the use of a logic simulation tool designed for pedagogical purposes. Digital logic is commonly taught either completely theoretically or together with practical work on breadboards using Small Scale Integration (SSI) devices. Such practical work is limited in scope and often teaches more about how to connect wir...

We present a flexible time-domain synthetic aperture radar signal simulation system. We demonstrate its use in simulating clutter, stationary and moving targets. The point target analysis shows that the observed impulse response agrees with theoretical values. Clutter results how that the observed clutter corresponds to K distribution model. We also demonstrate that the system may be used for t...

A new method for hierarchical fault simulation based on multilevel Decision Diagrams (DD) is proposed. We suppose that a register transfer level (RTL) information along with gate-level descriptions for blocks of the RTL structure are available. Decision diagrams (DDs) are exploited as a uniform model for describing circuits at these representation levels. The approach proposed allows to reduce ...

Recently, an incremental algorithm (incremental-in-space algorithm) for digital simulation has been studied with good results in speeding up simulation. In this paper we present another algorithm (incremental-in-time algorithm) for incremental simulation of digital circuits. The incremental-inspace algorithm pessimistically resimulates the circuit components that could be affected by design cha...

We describe a method for integrating information from lens design into image system simulation tools. By coordinating these tools, image system designers can visualize the consequences of altering lens parameters. We describe the critical computational issues we addressed in converting lens design calculations into a format that could be used to model image information as it flows through the i...

This manuscript describes a method for using digital-video technology to create patient simulations in which the simulated patient is always active on the computer screen. We outline the technical method we have developed, and we present the lessons learned in applying the method to develop a prototype patient simulation.
