Shield count minimization in congested regions

Prashant Saxena, Satyanarayan Gupta
2002 Proceedings of the 2002 international symposium on Physical design - ISPD '02  
We address this problem at both the methodological and algorithmic levels in this paper, integrating the traditionally separate steps of power and signal routing in a safe manner to minimize the number  ...  This is commonly done by adding shields adjacent to these wires. However, the number of wires requiring shields in high frequency designs becomes extremely large, resulting in a large area impact.  ...  The shield count minimization techniques discussed in this paper were applied to the interconnect trunks routed in M3.  ...

Probabilistic congestion model considering shielding for crosstalk reduction

Jinjun Xiong, Lei He
2005 Proceedings of the 2005 conference on Asia South Pacific design automation - ASP-DAC '05  
probabilistic congestion model considering shielding enables shielding reservation and minimization for routing and achieves routing congestion (or area) reduction by 47.7% (or 31.0%) on average under  ...  the given routing area (or congestion) constraints, when compared to the above deterministic congestion model not able to estimate shielding and therefore not able to minimize shielding during routing  ...  Therefore, minimizing the number of shields due to shielding is very valuable for congestion reduction.  ...

Full-chip multilevel routing for power and signal integrity

Jinjun Xiong, Lei He
2007 Integration  
The proposed design methodology is a one-pass solution to the co-design of power and signal networks in the sense that no iteration between them is required in order to meet design closure.  ...  Such a separated approach results in slow design convergence for wirelimited deep sub-micron designs.  ...  We also compare the runtime in seconds in column 6 and 11 of Table 2 .  ...

Cross talk driven placement

Jinan Lou, Wei Chen
2003 Proceedings of the 2003 conference on Asia South Pacific design automation - ASPDAC  
Furthermore, due to reduced coupling capacitance, the design speed is 8% faster on average in comparison with traditional timing-driven, congestion-aware placement flow.  ...  By addressing cross talk at placement level with this algorithm, the value and count of the highest post route peak noise were successfully reduced in a set of industrial benchmarks.  ...  Even for the same design, the congestion tends to differ drastically from region to region.  ...
