1.删除一条net的一部分

setLayerPreference node_layer -isVisible 0
setLayerPreference G2 -isVisible 1
editCutWire -only_visible_wires -line {a b c d}
selectWire e f g h 11 VSS
deleteSelectedFromFPlan

2.删除线和孔的命令可以用

select_obj $aaa

editDelete -selected

3.addStripe命令

addStripe -nets "VDD2H" -layer G1 -direction horizontal -area "a b c d" -width 10.8 -spacing 3.6 -number_of_sets 1 -stacked_via_top_layer G1 -stacked_via_bottom_layer G1 -uda GlobalG1

加入PG stripe的命令，-uda是table

-number_of_sets/-set_to_set_distance：即为stripe和stripe之间的pitch

editDelete -subclass GlobalG1，即可删除uda

4.editPowerVia命令

editPowerVia -bottom_layer G1 -top_layer G2 -add_vias 1 -area "a b c d"

5.dbShape [dbShape [dbGet top.fPlan.boxes ] SIZEY -1.344 SIZEX -1.68] -output polygon

出来的是四个点的坐标

6.createRow

-site 指定site的名字

-polygon：偶数个坐标指定create的区域

-flip1st :Controls the orientation of the first (bottom) row, which is R0 by default. When -flip1st, the first row's orientation is MX.

7.加入一些cell，但又不想有以下操作，setEcoMode
