原文 For clock trees, the traditional way is to go with zero skew or balanced skew. For each of the sinks, the insertion delay is kept to be equal so that each node receives the clock at the same time(or as close as physically possible). Here, your clock design is completely inde...

In this paper we propose an object oriented approach for reusing presynthesized components in VLSI design. Each component object has an interface which hides its internal implementation details and yet allows the operations, per-formed by the component, to be invoked by sending an appropriate message...
The proof is based on the reduction from 3SAT problem. The result of this paper would become an important base for various types of the intentional-skew-aware system optimization problems.Takayuki OBATAMineo KANEKO電子情報通信学会技術研究報告. VLSI設計技術. VLSI Design Technologies...
Few people will question that the clock is the single most critical signal in System-on-a-Chip (SoC) design. This is the net which first encountered the deep submicron challenges: interconnect delay, coupling noise, IR drop, electro-migration, process va

This paper proposes a Design of Temperature Variation-Insensitive Cellular Oscillator Circuits for CMOS High-Speed Low-Skew VLSI. A simulation results proves that maximum clock skew has less than 0.4% of a system clock period, this technique can be used for a low shew clock distribution in a ...

In 21st-Century VLSI design, clocking plays crucial roles for both performance and timing convergence. Due to their non-convex nature, optimal minimum-delay/area zero-skew wire-sizing problems have long been considered intractable. None of the existing approaches can guarantee optimality for general ...
