请问，做完floorplan大概根据什么指标比较好坏，不是一般都要place完以后，才能大概有个比较的结果吗

How to floorplan?
the key points need to be considered
1.data flow and pin location--->Macro location
                                    ---->Macro group
                                    ---->Module placement guide( region | fence | guide)
2.power/IR ----> Macro channel (to place pso cell)
               ----> stand cell area shape
3.Congestion/density  ----> Macro orient
                              ----->placement blockage ( hard | soft | partial)
How to judge qor of floorplan?
The module distribution should not be :
* Macros placed far from their related modules or connected I/Os.
* Too many wire cross-overs among modules, macros, and I/Os.
* Too many macro-to-macro, or module-to-module, overlaps.
* Too many "dead" areas in the design (that is, holes in the middle of placed macros).
* Inadequate macro orientation or spacing.
