EDB: IPC2581 export

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

Perform required imports

Perform required imports, which includes importing a section.

import os

import pyedb
from pyedb.generic.general_methods import (
    generate_unique_folder_name,
    generate_unique_name,
)
from pyedb.misc.downloads import download_file

Download file

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

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


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

print(targetfile)

C:\Users\ansys\AppData\Local\Temp\pyedb_prj_9MU\edb/ANSYS-HSD_V1.aedb

Launch EDB

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

edb = pyedb.Edb(edbpath=targetfile, edbversion="2024.1")

Parametrize net

Parametrize a net.

edb.modeler.parametrize_trace_width("A0_N", parameter_name=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,
