The alignment problem of movable terminals is subject to the constraint that the number of vertical tracks used is not increased in the process. This constraint is not considerated in the paper referred to [6] which first considered the alignment problem of movable terminals. This problem is ...
Each edge in E implies the presence of a set of routing tracks in k layers connecting adjacent vertices. An extended global routing solution is an edge labeling S such that for each edge e there is a label S(e)=(s1,s2,s3,…,sk), where each si for 1⩽i⩽k is a sequence of ...
用命令init_power_mesh_mapping 读入该文件。 在这个文件中,每层layer 只有一个值,用来模拟std cell 跟Macro 上的power density. Mixed Placer 会根据这个值删掉一些routing tracks. 因为每个设计macro 的数量跟类型都不同,所以power densinty 也不同。 Physical cells insertion and power routing 在执行完"refine...
Following global routing, each net undergoes detailed routing. The objective of detailed routing is to assign route segments of signal nets to specific routing tracks, vias, and metal layers in a manner consistent with given global routes of those nets.
We develop new algorithmic techniques for VLSI detailed routing. First, we improve the goal-oriented version of Dijkstra’s algorithm to find shortest
We have run the algorithm on large test cases; and experimental results show that we can achieve significant routability within a few number of available tracks. 展开 关键词: datapath congestion simultaneous routing multicommodity flow probability ...
In the detailed routing for VLSI standard cell layout design, the over-the-cell channel routing, which utilizes the over-the-cell region as the routing region, has been proposed. In this design method, after determining the net assignment to each channel in the global routing step, the track...

operating frequency, the effect of crosstalks on performance and even on yield in integrated circuit design and manufacturing thus increases rapidly. Consequently, reduction of crosstalks between interconnection wires has become important in VLSI (very large scale integration) design. In this ...
A technique for routing signal wires in an integrated circuit design includes applying a first rule that attempts to route a signal wire along existing power supply shapes of the integrated circuit design and applying a second rule that provides shield wires along segments of the signal wire that...
