EDB: Importing GDS file#
This example demonstrates how to import GDS files and translate their information to an EDB file.
Perform imports.
[1]:
import os
import tempfile
from pyedb.dotnet.edb import Edb
from pyedb.misc.downloads import download_file
from ansys.aedt.core.hfss3dlayout import Hfss3dLayout
Case 1: Import a GDS file.#
Download the test case folder and copy it to a temporary folder. The following files are used in this example:
XML_Automation.xml defines physical information such as material properties, stackup layers, and boundary conditions.
Model.map maps properties to stackup layers.
[2]:
temp_dir = tempfile.TemporaryDirectory(suffix=".ansys")
control_fn = "Model.xml"
gds_fn = "Model.gds"
layer_map = "Model.map"
local_path = download_file("gds", destination=temp_dir.name)
my_control_file = os.path.join(local_path, control_fn)
my_map_file = os.path.join(local_path, layer_map)
gds_in = os.path.join(local_path, gds_fn)
Open EDB#
Import the gds and open the edb. Each gds is followed either by a control file (XML) or a technology file (IRCX, VLC.TECH, or ITF). Then a MAP file is also regularly used to map the stackup layers, and finally in some cases a layer filter (XML) is deployed, when only a part of the stackup is needed.
[3]:
# Select EDB version (change it manually if needed, e.g. "2025.1")
version = "2025.1"
print(f"EDB version: {version}")
edb = Edb(gds_in, edbversion=version, control_file=my_control_file, map_file=my_map_file)
# ## Plot stackup
edb.stackup.plot()
# ## Save and close EDB
#
# Save the project.
edb1_path = os.path.join(temp_dir.name, "gds_design.aedb")
edb.save_as(edb1_path)
# Close the project.
edb.close_edb()
# ## Open both EDB files with HFSS 3D Layout, and observe the design / confirm the robustness from GDS to EDB.
h3d_gds = Hfss3dLayout(project=edb1_path, version=version, new_desktop=True)
# ## Close the HFSS 3D Layout design and release the dekstop.
h3d_gds.release_desktop()
# Clean up the temporary folder.
temp_dir.cleanup()
