## goals

The participants have acquired basic knowledge of computer-aided engineering work using the example of SPICE and Mathematica. They both got to know simulators and understand how to apply them. Practical exercises are selected with a view to the contents of the study of electrical engineering and information technology. Both parts are divided into lectures in the lecture hall HID and exercises at the CIP pool of the Department of Electrical Engineering and Information Technology.

## content

The course "Computer aided circuit analysis" consists of two parts: Part I: Introduction to circuit simulation with "SPICE" Part II: Introduction to the computer algebra system (CAS) "Mathematica".

In the first part the students learn to describe circuits (amplifier, filter, DC-AC converter) on the netlist level and as a circuit diagram, and to simulate them in both time and frequency domain. It is shown how the models of the components (transistors, operational amplifiers, resistors, etc.) are created and adapted. In addition, the operation of the simulator itself is addressed in order to adjust it to the requirements of the analysis.

In the second section, students are taught the structure of the computer algebra system Mathematica so that they can solve mathematical problems symbolically and numerically. Various examples, from linear systems of equations up to differential equations are addressed. Solutions are represented with the help of curves and figures.
