摘　　要：为实现宏单元(Macro)的自动摆放,针对Innovus的超级命令PlanDesign展开研究,分别以Module与Marco作为目标种子,对不同约束条件进行多次实验,得出结果最佳的约束条件,并将实验结果与已经流片的Floorplan在时序、时间、功耗和时钟关键节点分布进行对比。结果表明:2种自动摆放Macro的约束条件均可以比人工节省80%的时间;功耗分别下降约5%和3.3%;时钟关键节点更加密集。In order to realize automatic placement of the macrocells, the innovus′s super-command Plan Design was studied.With Module and Marco as the target seeds, multiple experiments were carried out for different constraints, and the best constraints were obtained. The experimental results are compared with the tapeout′s Floorplan in terms of timing, time, power consumption, and CTS key node distribution. The results show that the two automatic placement of Macro constraints can save 80% of the time compared to manual;the power consumption drops by respectively about 5% and 3.3%, respectively;the clock key nodes are more dense.
