How to make the Power/Ground Identification nets only the GND

[WengCQ1]

How could I to set the reference net only the GND net?
Most of time it has several nets in it:

I want to use the Pyedb to set only GND in the Power/Ground nets identification list.

Thanks!

Hi @WengCQ1,
in pyedb this can be done very easily.
Here is a small code snippet

from pyedb import Edb
from ansys.aedt.core import generate_unique_folder_name
from ansys.aedt.core.downloads import download_file
 
output_project = r"D:\Temp\demo.aedb"
temp_folder = generate_unique_folder_name()
targetfile = download_file("edb/ANSYS-HSD_V1.aedb", destination=temp_folder)
 
ansys_version = "2ß25.1"
 
edb = Edb(edbpath=targetfile, edbversion=ansys_version)

for net_name, net in edb.nets.power.items():
    if net.is_power_ground and not net_name.lower() == "gnd":
        net.is_power_ground = False
edb.save()
edb.close()
