Check whether the Io Filler's PG pin had been connected to the PG NET.
If not, there need GNC(Global Net Connection).

In encounter , I have not deal with PG pin or PG net, but I know all of the IO PAD have the PG pin, why they (except the VDD and VSS IO PAD) have not short errors ?

but I will try your method, Thanks!
