Functional verification and Virtual Test, which is verification of a test procedure, of mixed-signal circuits share the need for efficient simulation capabilities. Switching DC/DC converters are a particularly hard problem, because traditional SPICE-type simulation approaches incur simulation efforts which prevent one from covering all conceivable use-cases. The new IEEE 1800-2012 standard for SystemVerilog...
In this paper, the skew by data dependent gate loading has been analyzed. A method based on the concept of MOS parametric capacitance has been proposed. According to different data dependent of the MOS transistor, including transient channel charge and Miller effects, the values of capacitance in different data loadings have been extracted. Two clock tree routes have been analyzed by using the gate...

A novel methodology for accurate and efficient static timing analysis is presented in this paper. The methodology is based on finding a frequency domain model for the gates which allows uniform treatment of the gates and interconnects. It is shown that despite the highly nonlinear overall gate model, a frequency domain model of the gate with the model parameters, gate moments, as functions of the...
A physical yet analytical phase change memory (PCM) model simultaneously accounting for thermal and electrical conductivities is presented. Due to the physics based nature of the model, the essential temperature from heating and cooling of PCM during operation is instantaneously updated. More importantly, the model can be applied to non-conventional circuit design technique. We show that for the first...
This paper describes an analysis of the transient response of an orthogonal core-type dc-ac converter for use in a photovoltaic power system. The analysis is based on a numerical model of an orthogonal core for use with the SPICE circuit analysis program. As one example of such a transient response analysis, we calculated the voltage and current of the dc-ac converter when its secondary is cut off...
