|Integrated Circuit/EM Simulation and Design Technologies for Advanced Radio Systems-on-chip|
Integrated circuits (ICs) are miniaturized and complex electronic circuits (consisting of, amongst others, semiconductor devices and passive components such as e .g. resistors and capacitors). Miniaturisation has put components very close to each other. The overall designs are mathematically large and include a lot of electromagnetic coupling. For planned developments of wireless communication channels in the SHF and EHF bands, integrated circuit (IC) design automation tools are indispensable. These tools are needed to develop nanoscale designs of unprecedented complexity and performance and, in addition, enable the achievement of single-pass design success to avoid costly re-spins and the loss of market opportunities.
The mathematical part in IC design refers to the physical mapping of the devices with equations describing the various realations. such as positioning, geometry and wiring of electronic devices, nonlinear behaviour (transistors), responses in time and frequency domain, inductive coupling and tuning of oscillators. Dealing with IC design of mobile devices in hitherto unsused bandwiths in ICESTARS the "behaviour" of the designed ICs is simulated before thr expensive manufacturing process starts.
Today's RF design in super high and extremely high frequencies is not functionally adequate when it comes to solving technical gaps, such as, amongst others, accurate performance prediction of "large" chips or modules operating in the SHF and EHF range. The ICESTARS research focusses on bridging such technical gaps by developing and implementing mathematical methods such as developing new algorithms for, e.g., electromagnetic simulation, model extraction and optimisation tools.
