小菜请教高手

Warning: Design has unannotated primary inputs. (PWR-414)
Warning: Design has unannotated sequential cell outputs. (PWR-415)
我在dc综合时,每次都在报告中,出现上面两个问题.
不明白什么意思.那为大牛能告诉下是什么意思么?
并说下该真么改正?
谢谢了啊

最好的办法：dc-shell>man"PWR-414"

Anumberof primary input ports of your design are not user annotated
with switching activity. Default switching activity values are used for
these ports. This may result in inaccurate power numbers.
