This paper proposes a new approach to analyze crosstalk of coupled interconnects in the presence of process variations. The suggested method translates correlated process variations into orthogonal random variables by principle component analysis (PCA). combined with polynomial chaos expression (PCE), the technique utilizes Stochastic Collocation Method (SCM) to analyze the system response of coupled...
Current mode (CM) scheme provides suitable alternative for the high speed on-chip interconnect signaling. This paper presents a energy-delay optimization methodology for the current-mode (CM) signaling scheme. Optimization for the CM circuits for on-chip interconnects requires a joint optimization of driver and receiver device sizes, as their parameters which affect the energy-delay performance depend...
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...
This paper presents a preliminary study of the chaotic behavior of servo-flap mid-span bending of a four-blade helicopter during hover, low and high-speed forward flights. The servo-flap vibratory measurement was used to create state vectors in a multidimensional space through time-delay embedding, and the trajectory of state vectors in the reconstruction state space was quantified using the correlation...
The commonly used switch factor (SF) based delay analysis can not provide an accurate delay value at the presence of coupling noise especially when aggressor signal arrives after the victim signal have passed the threshold voltage. Therefore, full waveform accuracy must be used to accurately predict the signal delay. In this paper, a closed form expression of the output waveform is derived for the...
