Import Setup AC#

This example shows how to import SIwave, HFSS setups for AC analysis. In this example, we are going to

  • Download an example board

  • Create a configuration file

    • add setups

  • Import the configuration file

Import the required packages#

[1]:
import json
from pathlib import Path
import tempfile

from ansys.aedt.core.downloads import download_file

from pyedb import Edb

AEDT_VERSION = "2024.2"
NG_MODE = False

Download the example PCB data.

[2]:
temp_folder = tempfile.TemporaryDirectory(suffix=".ansys")
file_edb = download_file(source="edb/ANSYS-HSD_V1.aedb", destination=temp_folder.name)

Load example layout.#

[3]:
edbapp = Edb(file_edb, edbversion=AEDT_VERSION)
PyAEDT INFO: Logger is initialized in EDB.
PyAEDT INFO: legacy v0.31.0
PyAEDT INFO: Python version 3.10.11 (tags/v3.10.11:7d4cc5a, Apr  5 2023, 00:38:17) [MSC v.1929 64 bit (AMD64)]
PyAEDT INFO: Database ANSYS-HSD_V1.aedb Opened in 2024.2
PyAEDT INFO: Cell main Opened
PyAEDT INFO: Builder was initialized.
PyAEDT INFO: EDB initialized.

Create an empty dictionary to host all configurations.#

[4]:
cfg = dict()

Create an SIwave SYZ setup#

    • type. Type of the sweep. Supported types are ‘interpolation’, ‘discrete’, ‘broadband’.

    • frequencies. Frequency distribution.

      • distribution. Supported distributions are ‘linear_count’, ‘linear_scale’, ‘log_scale’.

      • start. Start frequency. Example, 1e6, “1MHz”.

      • stop. Stop frequency. Example, 1e9, “1GHz”.

      • increment.

    ],
}

Add setups in configuration#

[7]:
cfg["setups"] = [siwave_setup, hfss_setup]

Write configuration into as json file#

[8]:
file_json = Path(temp_folder.name) / "edb_configuration.json"
with open(file_json, "w") as f:
    json.dump(cfg, f, indent=4, ensure_ascii=False)

Import configuration into example layout#

[9]:
edbapp.configuration.load(config_file=file_json)
edbapp.configuration.run()
[9]:
True

Review#

[10]:
edbapp.setups
[10]:
{'hfss_1': <pyedb.dotnet.edb_core.utilities.hfss_simulation_setup.HfssSimulationSetup at 0x1fc172553f0>,
 'siwave_1': <pyedb.dotnet.edb_core.utilities.siwave_simulation_setup.SiwaveSimulationSetup at 0x1fc182c22f0>}

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.

[11]:
edbapp.save()
edbapp.close()
