A 3-D Fast transform-based preconditioner for large-scale power grid analysis on massively parallel architectures
Daloukas, K.; Evmorfopoulos, N.; Tsompanopoulou, P.; Stamoulis, G. I. (2014)Efficient analysis of on-chip power delivery networks is one of the most challenging problems that EDA is confronted with. This paper addresses the problem of simulating general multi-layer power delivery networks with ... -
Characterization of the worst-case current waveform excitations in general RLC-model power grid analysis
Evmorfopoulos, N.; Rammou, M. A.; Stamoulis, G.; Moondanos, J. (2010)Validating the robustness of power distribution in modem IC design is a crucial but very difficult problem, due to the vast number of possible working modes and the high, operating frequencies which necessitate the modeling ... -
Fast and accurate BER estimation methodology for I/O links based on extreme value theory
Cevrero, A.; Evmorfopoulos, N.; Antoniadis, C.; Ienne, P.; Leblebici, Y.; Burg, A.; Stamoulis, G. (2013)This paper introduces a novel approach towards the statistical analysis of modern high-speed 110 and similar communication links; which is capable of reliably to determine extremely low (-10-2 or lower) bit error rates ... -
Fast Transform-based preconditioners for large-scale power grid analysis on massively parallel architectures
Daloukas, K.; Evmorfopoulos, N.; Drasidis, G.; Tsiampas, M.; Tsompanopoulou, P.; Stamoulis, G. I. (2012)Efficient analysis of massive on-chip power delivery networks is among the most challenging problems facing the EDA industry today. In this paper, we present a new preconditioned iterative method for fast DC and transient ... -
A macromodel technique for VLSI dynamic simulation by mapping pre-characterized transitions
Bountas, D.; Stamoulis, G.; Evmorfopoulos, N. (2008)Accurate simulation of digital circuits is an essential part of the design process. High precision models are generally used to confirm logic behavior and estimate power dissipation, which has become an extremely important ... -
A parallel fast transform-based preconditioning approach for electrical-thermal co-simulation of power delivery networks
Daloukas, K.; Marnari, A.; Evmorfopoulos, N.; Tsompanopoulou, P.; Stamoulis, G. I. (2013)Efficient analysis of massive on-chip power delivery networks is among the most challenging problems facing the EDA industry today. Due to Joule heating effect and the temperature dependence of resistivity, temperature is ... -
Precise identification of the worst-case voltage drop conditions in power grid verification
Evmorfopoulos, N.; Karampatzakis, D.; Stamoulis, G. (2006)Identifying worst-case voltage drop conditions in every module supplied by the power grid is a crucial problem in modern IC design. In this paper we develop a novel methodology for power grid verification which is based ... -
Selective inversion of inductance matrix for large-scale sparse RLC simulation
Apostolopoulou, I.; Daloukas, K.; Evmorfopoulos, N.; Stamoulis, G. (2014)The inverse of the inductance matrix (reluctance matrix) is amenable to sparsification to a much greater extent than the inductance matrix itself. However, the inversion and subsequent truncation of a large dense inductance ...
