We present a programmable method for shift-clock stagger assignment to reduce power supply noise during system-on-chip (SoC) testing. An SoC design is typically composed of several blocks and two neighboring blocks that share the same power rails should not be toggled at the same time during shift. Therefore, the proposed programmable method does not assign the same stagger value to neighboring blocks...
On the basis of recursive trees, we propose a new kind of deterministic recursive trees (DRT) with a feature that the initial state of recursive trees is a lattice with an arbitrary number of nodes. In the subsequent evolving step, existing nodes create finite nodes. We obtain analytical formulae for degree distribution and average path length. We also study mean first passage time (MFPT) between...
In this work, we modeled three Cu-plug through silicon vias (TSVs). The three coaxial TSVs are based on the coaxial transmission line and are simulated using two methods. The first method is using an EM field solver such as HFSS. The second method is derived from a set of analytical resistance-inductance-capacitance-conductance (RLCG) equations derived from the physical dimensions of the three coaxial...
On the basis of the recursive trees, we propose a kind of delayed recursive trees with the feature that not all the existing nodes produce new nodes in each evolving step. Using the solutions of difference equation, the analytical expression of the average distance is obtained. This family of delayed recursive trees exhibits small-world characteristics. In addition, the average distance of this delayed...
For the special different nature images, we could hardly find particularly desirable approach, and there always exist Gibbs-type artifacts in the results of most methods. A novel Partial Differential Equation (PDE) model is proposed based on image feature for images denoising. The PDE model is adaptive within each region according to the details of the image feature to adjust the size of the diffusion...
Precision positioning performance is degraded by nonlinear effects of dynamic error and flexibility with harmonic drive systems. To compensate for dynamic error in the presence of nonlinear flexibility in high precision tracking, the nonlinear dynamic equation with dynamic error of harmonic drive is established by Lagrange method. Then, it is inverted to the state equation for control design. The...
