Fixed-outline floorplanning: enabling hierarchical design

S.N. Adya, I.L. Markov
2003 IEEE Transactions on Very Large Scale Integration (vlsi) Systems  
Our proposed moves are based on the notion of floorplan slack.  ...  When Simulated Annealing is used, e.g., with the Sequence Pair representation, the typical choice of moves is fairly straightforward.  ...  This implies multi-objective minimization. Typically, most simulated annealing based floorplanners use a linear combination of area and wirelength as an objective for the annealer.  ...

REWIRE: An optimization-based framework for unstructured data center network design

Andrew R. Curtis, Tommy Carpenter, Mustafa Elsheikh, Alejandro Lopez-Ortiz, S. Keshav
2012 2012 Proceedings IEEE INFOCOM  
Therefore, we propose a data center network design framework, REWIRE, that designs networks using a local search-based algorithm.  ...  DCN design is especially difficult when expanding an existing network, because traditional DCN design places strict constraints on the topology (e.g., a fat-tree).  ...  Therefore, we added the ability to seed REWIRE's simulated annealing procedure with a candidate solution. To find a seed candidate, we use a heuristic based on the spectral cap of a graph.  ...
