The performance of high-speed VLSI circuits is increasingly limited by interconnect coupling noise. In this paper we present a closed-form crosstalk noise model with accuracy comparable to that of SPICE for an arbitrary ramp input. We also develop a simplified delay model for estimating delays on coupled RC lines considering input slew times for both(More)
—We describe new, efficient algorithms for layout modification and phase assignment for dark field alternating-type phase shifting masks in the single exposure regime. We make the following contributions. First, we suggest new two-coloring and compaction approach that simultaneously optimizes layout and phase assignment which is based on planar embedding of(More)
Performance of high-speed VLSI circuits is increasingly limited by interconnect coupling noise. We present simple and improved analytical models for noise phenomena due to coupling capacitance. We extend the Π model presented in [4] to accommodate a segmented aggressor. We also include a linear driver resistance in the modeling of both victims and(More)
The performance of high-speed VLSI circuits is increasingly limited by i n terconnect coupling noise. We provide improved, easily computable estimates of crosstalk peak noise, as well as impact of coupling on aggressor delay, for distributed RC interconnects. Our approach is based on better modeling of the distributed interconnects, as well as more detailed(More)
