宏单元flash里面有一对电源地VPPVNN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 -cellsfzu8051_top_inst/FLASH_32KB
begin derive_pg_connection...

还有就是我在例化pad的时候，pad上面有两个pin，P是inoutPADR1是out的，我这样连接应该是对的吧?

create_net -power/ -ground
创建了，他说VPPVNN已经存在了
lz 最后怎么解决的呢 能分享一下嘛
你create_net加了power/ground 了?
