innovus，有scan chain是不是就不要设置setPlacemode了？

佬门，defIn scan.def，设置setPlaceMode

setPlaceMode -place_global_ignore_scan false
setPlaceMode -place_global_reorder_scan true

错误如下，我是不是要把这两句话删除了。



**ERROR: (IMPSP-9100): Scan chains exist in this design but are not defined for 70.89% flops and -place_global_ignore_scan is set to false. Placement and timing QoR can be severely impacted in this case!

It is highly recommend to keep -place_global_ignore_scan option as its default value 'true' with scan chains definition.
