宏单元flash里面有一对电源地VPP  VNN在连接电源地的时候，pad和宏单元的电源地没有连起来。然后就命令连接，出现了错误。
derive_pg_connection -power_net VPP -power_pin VPP -ground_net VNN -ground_pin VNN -cells  fzu8051_top_inst/FLASH_32KB
begin derive_pg_connection...
Error: Net VPP is not a power net. (MWUI-714)
derive pg failed

connect_net VPP [get_pins fzu8051_top_inst/FLASH_32KB/VPP]
Error: Objects 'VPP' and 'VPP' are at different levels in the design hierarchy.  Nets can be connected only to pins and ports at the same hierarchical level. (UIED-37)

connect_net VPP [get_pins io_pad_inst/VPP_PAD/PADR1]
Error: Objects 'VPP' and 'PADR1' are at different levels in the design hierarchy.  Nets can be connected only to pins and ports at the same hierarchical level.

还有就是我在例化pad的时候，pad上面有两个pin，P是inout  PADR1是out的，我这样连接应该是对的吧？

  PANALOG  VPP_PAD(.P(), .PADR1(VPP));
  PANALOG  VNN_PAD(.P(), .PADR1(VNN));
