Chapter 1 of the thesis
There exists
different circuit simulation environments for digital, analog and mixed signal circuitry.
Some of them are Ng Spice, GnuCap, Circuit Logix, LT Spice, Student version of
Multisim, Top spice, Circuitsimulator1.5j, Mac Spice, 5Spice, Beige Bag,
Micro-Cap 10, PECS, Proteus, QUCS, Solve Elec, Xspice, Pspice, Multisim,
SiMetrix, TINA, PowerSim.
Some of
them are freely available while others are licensed versions. Among these
circuit simulators most popular simulators are MultiSim, Pspice.
Multisim
is the circuit simulation environment from National Instruments. It is widely
used by designers, researchers, students, academicians, professionals. Its rich
features are tailored according to the needs of different profiles. In
designers version it has features such as
(a)
Industry standard component list: which helps the design to be on par
with industry standard components that are in manufactures catalogs.
(b)
Customized symbols: Designer is given the privilege to
create his own symbols and make use of it in his/her design when standard
symbols does not suit their needs.
(c)
Multiple designs: Designer can create complex
circuits in multiple schematics and stills can work on all of them together. Compare
and simulate their results.
(d)
Interface with other simulation
environment:
Designer can interface with other simulation environment such as PSPICE using
Spectre.
(e)
Advanced analysis of the circuit: it helps in going to minute
details of circuit. Studying the minute
details will help greatly to design efficient circuits.
(f)
Easy to debug, reduces errors and ultimately an
optimized circuit can be produced.
The student’s
version of Multisim is made available for free but with limited access to
components lists, circuit simulation tools etc., The Student version of
MultiSim has a variety of features such as
(a)
Easy to draw schematics : From the given component list
students can easily draw the circuit.It is easy to locate different components
that are readily available
(b)
3D animations: 3D animations of prototype board, circuit
components help students to easily interpret with real components. It helps
students enjoy learning.
(c)
Easy to do circuit simulations: Circuit simulation is simple. And
students can easily verify their manually done results with circuit simulation
results.
(d)
Better understanding of theory: It helps students to visualize
circuits and understand the theory behind it. Hands on experiences in building
the circuits will reinforce the better understanding of the theory.
(e)
Student Design Projects: Student version of MultiSim is
provided with decent component lists, components list that are manufacturer
specific ,which in turn gives student privilege to build academic design projects.
(f)
Integrating Multisim with NI ELVIS: MultiSim when integrated with NI
ELVIS(National Instruments Educational Laboratory Virtual Instrumentation
Suite) is very helpful in analyzing analog circuits.
(g) Interfacing
MultiSIm with NI My DAQ: When NI MultiSim integrated with Ni My DAQ students
can simulate all kinds of circuits from complex to simple.
questions I need to answer....
