在placeDesign的时候,报如下的错误,这是不是由于扫描链没有配置所致?请问如何配置扫描链?
**ERROR: (IMPSP-9099): Scan chains exist in this design but are not defined for 54.84% flops. Placement and timing QoR can be severely impacted in this case!
It is highly recommend to define scan chains either through input scan def (preferred) or specifyScanChain.
