Timing-Driven Bipartitioning with Replication Using Iterative Quadratic Programming
ثبت نشده
چکیده
We present an algorithm for solving a general min-cut, twoway partitioning problem subject to timing constraints. The problem is formulated as a constrained programming problem and solved in two phases: cut-set minimization and timing satisfaction. A mathematical programming technique based on iterative quadratic programming (TPIQ) is used to find an approximate solution to the constrained problem. When the timing constraints are too strict to have a feasible solution, node replication is used to satisfy the constraints. Experimental results on ISCAS89 benchmark suite show that TPIQ can solve the timing-driven bipartitioning problem with little impact on the chip size.

متن کاملAn iterative method for tri-level quadratic fractional programming problems using fuzzy goal programming approach
Tri-level optimization problems are optimization problems with three nested hierarchical structures, where in most cases conflicting objectives are set at each level of hierarchy. Such problems are common in management, engineering designs and in decision making situations in general, and are known to be strongly NP-hard. Existing solution methods lack universality in solving these types of pro...
متن کاملReplicated partitioning for undirected hypergraphs
Hypergraph partitioning (HP) and replication are diverse but powerful tools that are traditionally applied separately to minimize the costs of parallel and sequential systems that access related data or process related tasks. When combined together, these two techniques have the potential of achieving significant improvements in performance of many applications. In this study, we provide an app...
متن کاملA New Mathematical Approach based on Conic Quadratic Programming for the Stochastic Time-Cost Tradeoff Problem in Project Management
In this paper, we consider a stochastic Time-Cost Tradeoff Problem (TCTP) in PERT networks for project management, in which all activities are subjected to a linear cost function and assumed to be exponentially distributed. The aim of this problem is to maximize the project completion probability with a pre-known deadline to a predefined probability such that the required additional cost is min...
متن کاملRecent directions in netlist partitioning: a survey
This survey describes research directions in netlist partitioning during the past two decades in terms of both problem formulations and solution approaches. We discuss the traditional min-cut and ratio cut bipartitioning formulations along with multi-way extensions and newer problem formulations, e.g., constraint-driven partitioning (for FPGAs) and partitioning with module replication. Our disc...
