WebMulti-domain clock skew scheduling was proposed to tackle this impracticality by constraining the total number of clock delays. Even though this problem can be formulated as a mixed integer linear programming (MILP), it is expensive to solve optimally in general. In this paper, we show that, under mild restrictions, the underlying domain ... WebA clock distribution network must be synthesized such that the clock signal is delivered to each register with the proper delay to satisfy the clock skew schedule T CD. …

Webprocess variations, it is difﬁcult to implement clock schedule with a large set of arbitrary delays. In practice, it is desirable that the clock skew scheduling is constrained to a limited number of skew domains. Multi-domain clock skew scheduling (MDCSS) was ﬁrst proposed by Ravindran et al. [4] to meet this practical design requirement. http://users.eecs.northwestern.edu/~haizhou/publications/dac11.pdf
