EDB: IPC2581 export

This example shows how you can use PyAEDT to export an IPC2581 file.

Perform required imports

Perform required imports, which includes importing a section.

import os
import pyaedt

Download file

Download the AEDB file and copy it in the temporary folder.

temp_folder = pyaedt.generate_unique_folder_name()
targetfile = pyaedt.downloads.download_file('edb/ANSYS-HSD_V1.aedb', destination=temp_folder)


ipc2581_file = os.path.join(temp_folder, "Ansys_Hsd.xml")

print(targetfile)

D:\Temp\pyaedt_prj_2LL\edb/ANSYS-HSD_V1.aedb

Launch EDB

Launch the pyaedt.Edb class, using EDB 2023 R2 and SI units.

edb = pyaedt.Edb(edbpath=targetfile, edbversion="2023.2")

Parametrize net

Parametrize a net.

edb.modeler.parametrize_trace_width(
    "A0_N", parameter_name=pyaedt.generate_unique_name("Par"), variable_value="0.4321mm"
)

True

Cutout

Create a cutout.

signal_list = []
for net in edb.nets.netlist:
    if "PCIe" in net:
        signal_list.append(net)
power_list = ["GND"]
edb.cutout(signal_list=signal_list, reference_list=power_list, extent_type="ConvexHull",
           expansion_size=0.002,
           use_round_corner=False,
           number_of_threads=4,
           remove_single_pin_components=True,
           use_pyaedt_extent_computing=True,
           extent_defeature=0,
           )

True

Plot cutout

Plot cutout before exporting to IPC2581 file.

edb.nets.plot(None, None, color_by_net=True)

Create IPC2581 file

Create the IPC2581 file.

edb.export_to_ipc2581(ipc2581_file, "inch")
print("IPC2581 File has been saved to {}".format(ipc2581_file))

IPC2581 File has been saved to D:\Temp\pyaedt_prj_2LL\Ansys_Hsd.xml

Close EDB

Close EDB.

edb.close_edb()

True
