Introduction of the state-of-the-art circuit simulation computer programs used in the modern engineering practice, as well as practicing their use and further deepening the skills obtained about the electronic circuits by solving practical simulation problems.

8.1. Introduction: the evolution of simulation programs, the history of the SPICE simulator and its versions, non-SPICE based simulators

8.2. Modeling issues, modeling of semiconductors, functional models

8.3. Basic algorithms of circuit simulation: operating point calculation, transient analysis, calculation of transfer characteristics

8.4. Fundamentals and syntax of the SPICE circuit definition language, simple circuits, node and component names, setting of values and subcircuits

8.5. Using individual analysis types: operating point calculation, transfer characteristics, sensitivity analysis, transient analysis, distortion calculation, small signal transfer function

8.6. Presentation of the simulation results: conventional output data structure, graphical representation, post-processing opportunities, parametric analysis

8.7. Using the schematic editor: editing diagrams, symbols and symbol library operations

8.8. Block-based and multi-level diagrams, interfacing to PCB design programs

8.9. Simulation of digital and mixed signal circuits: functional analysis, delay effects and their consequences, input and output modeling of digital circuits, mixed signal simulation

8.10. Signal integrity simulation, usage of transmission lines, investigation of termination types (near-end and far-en terminations), investigation of the effect of capacitive loads

8.11. Simulation of high frequency circuits: the concept of scatter parameters and the usage thereof, simulation of the input reflection and transfer properties of attenuators and low-pass filters, introduction of filter design

8.12. Simulation of telecommunication systems, characterization of frequency mixers and amplifiers, investigation of a single-mixing heterodyne receiver

8.13. Circuit measuring exercise: operating point measurement of a transistor amplifier, comparison of the measured data with the simulation results, measurement of the driving range and its comparison with the simulation results

8.14. Circuit measuring exercise: introduction of the measurement of high frequency and microwave circuit components, investigation of the transfer and reflection of a filter and an amplifier, demonstration of large-signal properties, as well as the comparison of all these results with the simulated values

The lectures are held in a computer lecture room where the students individually perform the exercises as and which are set out by the instructor. The lectures consist of a theoretical introduction and of specific practical exercises completed by a simulation software. The subject also incorporates laboratory experiments two times.
