HFSS 3D Layout: PCB and EDB in 3D layout

This example shows how you can use HFSS 3D Layout combined with EDB to interact with a 3D layout.

import os
import tempfile
import pyaedt

tmpfold = tempfile.gettempdir()
temp_folder = os.path.join(tmpfold, pyaedt.generate_unique_name("Example"))
if not os.path.exists(temp_folder):
    os.makedirs(temp_folder)
print(temp_folder)

D:\Temp\Example_0NCGHE

Copy example into temporary folder

Copy an example into the temporary folder.

targetfile = pyaedt.downloads.download_aedb()
print(targetfile)
aedt_file = targetfile[:-12] + "aedt"

D:\Temp\PyAEDTExamples\edb/Galileo.aedb\edb.def

Set non-graphical mode

Set non-graphical mode. You can set non_graphical either to True or False.

non_graphical = False
NewThread = True

Set AEDT version

Set AEDT version.

aedt_version = "2024.1"

Initialize AEDT and launch HFSS 3D Layout

Initialize AEDT and launch HFSS 3D Layout. The h3d object contains the pyaedt.Edb class query methods.

d = pyaedt.launch_desktop(aedt_version, non_graphical, NewThread)
if os.path.exists(aedt_file):
    os.remove(aedt_file)
h3d = pyaedt.Hfss3dLayout(targetfile)
h3d.save_project(os.path.join(temp_folder, "edb_demo.aedt"))

True

Print boundaries

Print boundaries from the setups object.

h3d.boundaries

[]

Hide all nets

Hide all nets.

h3d.modeler.change_net_visibility(visible=False)

True

Show only two nets

Show only two specified nets.

h3d.modeler.change_net_visibility(["A0_GPIO", "A0_MUX"], visible=True)
edb = h3d.modeler.edb
edb.nets.plot(["A0_GPIO", "A0_MUX"])

Show all layers

Show all layers.

for layer in h3d.modeler.layers.all_signal_layers:
    layer.is_visible = True

Change layer color

Change the layer color.

layer = h3d.modeler.layers.layers[h3d.modeler.layers.layer_id("TOP")]
layer.set_layer_color(0, 255, 0)
h3d.modeler.fit_all()

Disable component visibility

Disable component visibility for "TOP" and "BOTTOM". The pyaedt.modules.LayerStackup.Layer.update_stackup_layer() method applies modifications to the layout.

top = h3d.modeler.layers.layers[h3d.modeler.layers.layer_id("TOP")]
top.is_visible_component = False

bot = h3d.modeler.layers.layers[h3d.modeler.layers.layer_id("BOTTOM")]
bot.is_visible_component = False

Fit all

Fit all so that you can visualize all.

h3d.modeler.fit_all()

Close AEDT

After the simulation completes, you can close AEDT or release it using the pyaedt.Desktop.release_desktop() method. All methods provide for saving the project before closing.

h3d.close_project()
d.release_desktop()

True
