Do we remove scan chain before placement and reconnected after routing ?

 Do we remove scan chain before placement and reconnected after routing ?

  •  It depends. In the past we always reordered the scan chains after placement. But lately, we haven't, because it can lead to hold violations. It may depend on your design and what speed you run scan at. The scan chain isn't really "removed", just reordered.
