CAD Lab is catering to the needs of the advanced facilities in "what-if" analysis for Electrical and Electronics Engineer. This lab consists of software MATLAB and PSPICE. The versatile nature of MATLAB allows "what-if" analysis that can be used to strengthen students understanding of electrical & electronics. MATLAB is useful in analyzing data obtained from laboratory experiments. In addition, it has been found that the interactive nature of MATLAB and its immediate graphing facilities are especially useful in enhancing the understanding of concepts and principles of electrical and electronics engineering fundamentals. SPICE is one of the most successful circuit simulation programs. Its widespread usage attests to the applicability of the program to large variety of circuit simulation problems. SPICE utilizes modified nodal analysis approach. It can be used for non-linear dc, non-linear transient and linear ac analysis problems. It can also be used to perform noise analysis, temperature analysis, Monte-Carlo analysis. One of the advantages of SPICE is its inclusion of device models for active devices such as diode, BJT, JFET, and MOSFET.
