Import Component Definitions

This example shows how to import component definitions. It includes

• Download an example board

• Create a config file with component RLC and solder ball information

• Apply the config file to the example board

Import the required packages

import json
from pathlib import Path
import tempfile

from IPython.display import display
from ansys.aedt.core.downloads import download_file
import pandas as pd

from pyedb import Edb

AEDT_VERSION = "2024.2"

Download the example PCB data.

temp_folder = tempfile.TemporaryDirectory(suffix=".ansys").name
file_edb = download_file(source="edb/ANSYS-HSD_V1.aedb", destination=temp_folder)

Load example layout.

edbapp = Edb(file_edb, edbversion=AEDT_VERSION)

Save and close Edb

The temporary folder will be deleted once the execution of this script is finished. Replace edbapp.save() with edbapp.save_as(“C:/example.aedb”) to keep the example project.

edbapp.save()
edbapp.close()
