BoxRouter: A New Global Router Based on Box Expansion …

WebJun 15, 2024 · These metal layers are usually represented by a coarse routing grid made up of gcells (global cells). The nets are globally routed as Steiner trees (Chap. 5, Sect. 5.6.1) and then detail-routed (Sect. 6.5.2). In an alternate approach, channels are created between the cells, but are limited to the internal cell layers such as Poly and Metal1 ... WebGlobal Routing by Integer Programming Suppose that for each net i, there are n i possible trees ti 1;t i 2;:::;t i n i to route the net. Constraint I: For each net i, only one tree ti j will be selected. Constraint II: The capacity of each cell boundary c peak district walks near derby

ILP-Based Global Routing Optimization with Cell Movements

WebA global routing is to find paths that connect the pins inside the G-cells through G(V,E) for every net. 2.3 Global Routing Metrics The key task of global router is to maximize the routabil-ity for successful detailed routing [24]. In addition, wire-length and runtime are other important metrics of global router.
