    Chapter 1


I am going to write chapter 1 of my thesis.All I know about the project is that I am going to do a microsoft visio   software for introductory electrical/electronics lab.

The targeted audience  are online engineering undergrad students who are not needed to come from a long distance to attend labs.

These are some details that I am able to find.

There are already some circuit  simulation environments available in the market.Software such as NI multi sim from National Instruments .Pspice from Cadence are few examples of circuit simulation environments.

NI multi sim has versatile features.They have  software for industrial circuit designers and researchers  and also they also have special software for academic purposes.

NI Multi sim for circuit designers and researchers includes featured areas such as

Aerospace and National Research Applications
Semiconductor Analysis ApplicationsLife Science, Medical Devices, and Bioinstrumentation ApplicationsEnergy and Power ApplicationsLow-Frequency Circuit Design for RF ApplicationsAutomotive Electronics Applications

NI Multi Sim for teaching applications includes

Analog Circuits and AnalysisDigital Logic Circuits, Microcontrollers, and FPGAsPower Electronics and SystemsStudent Design and Research Projects

We are now interested in only teaching applications of Analog circuits and  Analysis.
 NI Multi Sim is standard circuit design environment with integrated schematic capture and simulation.We can create a schematic by dragging and dropping the components and equipment from the list.Then connect them together using manual wiring or automatic wiring.And simulate the circuit for desired results.And results can be viewed in equipment or in the plots.

The circuit can be captured using the animations that are available in NI multi sim.This process includes selecting the components,wiring the schematic,simulating the circuits.And the desired results can viewed in equipment such as Digital Multi meters(DMM),Oscilloscope(CRO) or plots.



The other widely used software for simulations is PSpice .Pspice is a SPICE analog circuit and digital logic simulation program for Microsoft Windows.In pspice the circuit is described  to a  computer using  a file called circuit file.This contains circuit details such as the information about source and commands for what to do and what to display as output.The output is displayed in result file.

Different types of analysis such as DC analysis,AC analysis and transient analysis can be done using Pspice. There are other  basic components that are needed to be purchased additionally to add to the component list to work on a design .And for a beginner it is going to be hectic.

And I need to add details to multi sim and pspice features .And how they doesnot fit into our shoes.i.e how they are not  answering  our needs.And how they fail to acheive the purpose.Like in real  labs we will burn many resistors and diodes and transistors due high voltage and some components become short while others become open circuited.In mutli sim  schematic it is showing these details in schematic but not in animations.we wanted to add these details.And we need to add details that are usual in labs and that not included in multi sim.
Please help me  to prepare points that are available in multi sim and  pspice for simulations and the things that are lacking when compared to real lab situations.

we want provide a real experience to learner.

In chapter 1  I am supposed to write what is available in market .explain them.And where it fails to answering our needs. 
In chapter 2 I am supposed to write how i am answering these issues.
In chapter 3 thoery.
in chapter 4 how you make software.
In chapter 5 testing and evaluations.what can be done in future.

This is the plan .Now i need info for chapter 1.
