Versatile Algorithms For Nanoscale Designs
The Integrated Circuit/EM Simulation and Design Technologies for Advanced Radio Systems-on-chip (ICESTARS) project aims to develop and deploy integrated simulation algorithms and prototype tools that will overcome the barriers in existing and future radio frequency (RF) design flows.
RF designs are moving into higher frequencies and growing in complexity to meet the market demand for higher bandwidth and more functionality. "The project's research areas have been the efficient connection between the frequency domain, where the RF part of wireless transceiver systems is usually designed, and the time domain, where the digital signal processing and control logic are developed," says ICESTARS researcher Jan ter Maten.
The ICESTARS project developed a circuit simulation algorithm that produced a general mathematical framework for different classes of RF circuits by embedding the system of differential-algebraic equations (DAEs) into partial DAEs. The researchers say the ICESTARS algorithms have the potential to reduce the simulation overhead in the RF design process and improve the ability to augment chip development for the next several generations.
