Designing of interconnects and
pre-estimation of interconnect parameters are very important in radio frequency
(RF) and deep sub-micron technology for reducing delay, cross-talk, power
dissipation and noise and improving system performance. Then we can also
predict the actual behavior of designed circuit which is more close to
its physical implementation.
For simulating the interconnects and
prediction of its parameters we have built a parallel FDTD Maxwell Equation
Solver which can extract distributed parameters (R, L and C) from any given
type of 3D rectangular structure of VLSI chip. Interconnections will gain
even more importance as we continue reducing feature sizes of transistors
and enlarging chip area, and they may eventually become the dominant performance
limiting factors. It is commonly accepted that electrical performance of
ICs will be limited not by device switching speed, but by signal propagation
along the connection paths, and at very high frequency the distributed
parameters (i.e. Resistance, Capacitance, Inductance) dominate over lumped
parameters, and thus it degrades the circuit performance, speed and increases
the noise, delay and cross-talk. At very high frequencies these interconnects
work as transmission line and thus we have to solve the Maxwell Equations
for extracting the electromagnetic field around the interconnect structure.
We are using Finite Difference Time Domain (FDTD) method for solving Maxwell's
Electromagnetic equations.
In high-frequency
ranges, the present electronic design automation software has limited capabilities
to model electromagnetic (EM) systems where there are strong field effects
influencing their characteristics. In this situation, a full wave simulation
tool is desired for the analysis and design of high-speed. In the design
of high-frequency electronic systems such as radio-frequency (RF), microwave
and optical wave devices, computer aided design (CAD) plays an important
role in improving their performance and reducing their development cost.
Much electrical design automation (EDA) software is essential in the design
and analysis of analog and digital systems. Simulation is an essential
step in the analysis and design procedure. A good simulation will expose
and fix most problems during the development stage of the prototype system.
The objective was to design, develop, fabricate and test Micro-controller based Auto-Dialling System, for any exchange which accepts DTMF tone for sensing dialled number.
