Physical Design for Multichip Modules
… chip placement, global tree construction, and layer assignment. The emphasis is on maximizing the electrical performance, based on accurate modeling of MCM interconnect behavior. A new approach, called Reciprocal Expansion, is developed for rapidly estimating the time-domain response of lossy …

Genetic optimization applied to via and route strategy
… converted the via placement problem to a simpler layer assignment problem by enforcing the location of vias and pins to be the same. We then determined an optimal layer assignment given a set of flylines, i.e. logical connections, using a genetic optimization library called DEAP. We coined this …

The Retiming and Routing of VLSI Circuits
"Multi-layer technologies present additional challenges to the routing of the nets because the layer assignment can have a large impact on the net delays. Traditional approaches cause the first few nets to monopolize the ""good"" layers. Therefore, they perform poorly under the metric of minimizing …

Algorithmic studies on PCB routing
… of PCB routing: escape routing, area routing and layer assignment. Escape routing for packages and PCBs has been studied extensively in the past. Network flow is pervasively used to model this problem. However, previous studies are incomplete in two senses. First, none of the previous works …

New methods for electronic design automation problems
… solve the bus decomposition, escape routing, layer assignment and global bus routing. This problem was only partially addressed by Kong et al. (2009). In this dissertation, we present an ILP-based solution to the entire bus planning problem. We apply our bus planner to an industrial PCB (with …

Routing algorithms for electronic design automation
… increase the design complexity. The number of layers used also needs to be minimized in order to reduce the fabrication cost. To the best of our knowledge, no mature commercial automated router can handle these problems well. In this dissertation, both bus-based and net-based PCB routing …
