Hi,

Before detailed placement, all cell have illegal locations, and all of cell have "floating" attribute will be consider on the placer. Please check and make sure your cell's attribute is not "fixed". The data model commands on below are useful for you to debug the error:

data get $cell location
date put $cell location fixed
