Preface This book is compiled for the easier illustration of SPICE simulation and PCB designing to cater the syllabus of various Universities for the undergraduate level of Engineering. Each section has experiments described in a step by step manner.

This book is divided into five sections.

Introduction to EDWinXP, Introduction to EDSpice Simulator and the types of analysis that can be performed in EDSpice Simulator, EDSpice simulation experiments, SPICE circuit files, VHDL code samples, examples of 8051, AVR, PIC and Motorola microcontrollers and PCB design.

The EDSpice simulation experiments describes the Aim, Components required for the simulation, the circuit diagram, procedure, steps for the simulation and finally the result of the simulation. The Components required for the experiment is given as Type of Component – EDWinXP Component Name (Number of Components). The procedure section describes the method of simulating the circuit with the values to be assigned to each component in the circuit and the steps for simulating the circuit for the specified analysis. The result is obtained in the Waveform viewer.

SPICE section lists the *.cir files for the circuits that can be simulated in EDWinXP CIR file Editor.

VHDL simulation illustrates the list of experiments written in VHDL. The VHDL Editor in EDWinXP can be used for its simulation.

The microcontroller section give the real time simulation of the projects using different microcontrollers.

The PCB section describes the procedure of designing of PCB in EDWinXP.
