受教了，同时本人查阅了一下相关的ICC set_pnet_options 的可选项如下
ARGUMENTS
       -partial
              Allows  standard cells to be placed under pnets, but the pins in
              the standard cells are checked to prevent shorts with the pnets.
              The  -partial, -complete, and -none options control how the tool
              places the cell under the pnets.  These three options are  mutu-
              ally exclusive; you can specify only one.  If you do not specify
              any of these options, -none is used as the default.

       -complete
              Prevents cells from ever overlapping  with  pnets.   A  pnet  is
              treated  as  a  placement keepout.  The -partial, -complete, and
              -none options control how the tool places  the  cell  under  the
              pnets.   These  three  options  are  mutually exclusive; you can
              specify only one.  If you do not specify any of  these  options,
              -none is used as the default.

       -none  Allows  cells  to  be freely placed under pnets without checking
              for electrical shorts.  The pnets are  invisible  during  place-
              ment.   The  -partial,  -complete, and -none options control how
              the tool places the cell under the pnets.  These  three  options
              are mutually exclusive; you can specify only one.  If you do not
              specify any of these options, -none is used as the default.

其中default -none 对pnet下的stdcel pin 没有进行检查和限制 是free的，避免short应该是要注意要添加适合选项。
