Notes:
1.Stdcel:一般IP厂商同时提供CEL View+FRAM View, GDS+LEF;
2.Macro (包括Memory,PLL,IO等) :一般IP厂商只提供GDS+LEF,需要转
换到CEL View和FRAM View, 以便ICC使用;
3.LEFFRAM View,GDSCEL View:这个转换可以通过synopsys的
Milkyway工具;

Milkyway:CEL View vs. FRAM View
Notes: 物理实现阶段
1.物理实现阶段只需要FRAM View(不能缺),不需要CEL View;
2.工具只需要知道单元的物理尺寸多大,什么形状,端口从哪里连接,内部用了哪
些layer,什么地方不能让工具走线等等(FRAM View);
3.至于内部的细节(CEL View),不需要让工具知道,CEL View不需要被读入ICC
,节省内存,加快处理速度;
Notes:物理验证/流片
1.流片需要所有Cell的全部细节,要包括所有内部调用到Cell的GDS;

2.floorplan:Macro Cell的摆放
Macro摆放考虑:
1.有利于timing;
2.有利于congestion;
3.IR Drop考虑:robust + area4decaps
Macro摆放建议:
1.靠边摆放;
2.同一个hierarchy的macro尽量靠近摆放;
3.注意signal pin的方向,注意PG pin的分布;
4.注意Macro之间的连接关系,Hierarchy分析,DataFlow分析;
5.Macro的堆叠要考虑到对congestion、timing、si等的影响;
6.Leave some room for decap insertion;
7.可让工具自动粗略摆放,得到一个初始参考;

2.floorplan:PG Network
原则:
1.给所有Macro供上电;
2.给所有stdcel供上电;
3.As robust as possible;
4.最终评估标准要看:IR Drop;
建议:
1.查看stdcel的metal使用和方向,关注tf中各layer的方向;
2.查看macro的PG Pin的使用和方向(同时要注意macro的摆放方向);
3.确认当前使用的metal层数(M1-M6?);
4.考虑Top如何给当前block供电,连接关系;
5.注意macro之间的channel的供电;
6.基于以上因素,制定形成一个整体供电方案;
