aspiration

  本人小白一个，目前在学习icc，在练习lab3，执行 place_opt -area_recovery -optimize_dft -power 后报错，下面是log，请问该怎么解决。
  lab是2010的，icc是2018的

                                     This can hurt clock speed and routability of your design because
                                     placement considers scan nets to be just like any other net.
                                     Suggestion:  make a scandef file and note all register pins
