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

Perform imports and define constants#

Perform required imports.

[1]:

import json
import toml
from pathlib import Path
import tempfile

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

Define constants.

[2]:

AEDT_VERSION = "2025.1"

Download the example PCB data.

[3]:

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

Load example layout.#

[4]:

edbapp = Edb(file_edb, edbversion=AEDT_VERSION)

Apply config file#

[8]:

edbapp.configuration.load(cfg_file_path, apply_file=True)

[8]:

<pyedb.configuration.cfg_data.CfgData at 0x2871c6bcb80>

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.

[9]:

edbapp.save()
edbapp.close()
