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.

8.placeInst和addInst的区别在于 placeInst的对象是已在fp区域的inst,而addInst则是未在fp区域的inst。
9.报告出CTS后clock tree上的inverter和buffer的数量
10.报告当前design使用的view和corner用的命令:
all_rc_corner/all_delay_corners/all_setup_analysis_views
