本文简述了一种积木块式版图布线系统。它的特征是基于通道的定义和排序,动态地完成布线任务。它包括:一种层次式的自上而下的电源网布线和电源网的系统实现策略;一种结合了总体压缩的高效的多子图合并的总体布线方法。有效地匹配了通道的容量与布线区域的密度;带有通道压缩的L型通道和直通道的一体化通道布线完成了详细布线;环形通道的布线完成了包括电源网在内的I/O压焊块的连接。在测试标准例子的结果比较表明BROS要优于其它的BBL布线系统。
This article describes a block layout block layout system. Its characteristics are based on the definition and sequencing of channels, dynamic routing tasks completed. It includes: a hierarchical top-down power grid cabling and power grid system implementation strategy; combined with an overall compression of the efficient multi-subgraph consolidation of the overall wiring method. Effectively matching the capacity of the channel and the density of the wiring area; the integrated channel wiring with the channel compression L-shaped channel and the straight channel completes the detailed wiring; the circular channel wiring completes the I / O pressure including the power grid Block connection. The comparison of the results of the test standard examples shows that BROS is superior to other BBL cabling systems.
