PCIE virtual compliance#

This example shows how to generate a compliance report in PyAEDT using the VirtualCompliance class.

Keywords: Circuit, Automatic report, virtual compliance.

Perform imports and define constants#

Import the required packages.

[1]:
import os.path
import tempfile
import time

import ansys.aedt.core
from ansys.aedt.core.examples.downloads import download_file
from ansys.aedt.core.visualization.post.compliance import VirtualCompliance

Define constants#

[2]:
AEDT_VERSION = "2025.2"
NUM_CORES = 4
NG_MODE = False  # Open AEDT UI when it is launched.

Create temporary directory#

Create a temporary directory where downloaded data or dumped data can be stored. In this example, the temporary directory in where the example is stored and simulation data is saved. If you’d like to retrieve the project data for subsequent use, the temporary folder name is given by temp_folder.name.

[3]:
temp_folder = tempfile.TemporaryDirectory(suffix=".ansys")

Download example data#

[4]:
download_folder = download_file(
    source="pcie_compliance", local_path=temp_folder.name
)
project_folder = os.path.join(download_folder, "project")
project_path = os.path.join(project_folder, "PCIE_GEN5_only_layout.aedtz")

Launch AEDT and solve layout#

Open the HFSS 3D Layout project and analyze it using the SIwave solver. Before solving, this code ensures that the model is solved from DC to 70GHz and that causality and passivity are enforced.

[5]:
h3d = ansys.aedt.core.Hfss3dLayout(
    project=project_path, version=AEDT_VERSION, non_graphical=NG_MODE
)
h3d.remove_all_unused_definitions()
h3d.edit_cosim_options(simulate_missing_solution=False)
h3d.setups[0].sweeps[0].props["EnforcePassivity"] = True
h3d.setups[0].sweeps[0].props["Sweeps"]["Data"] = "LIN 0MHz 70GHz 0.1GHz"
h3d.setups[0].sweeps[0].props["EnforceCausality"] = True
h3d.setups[0].sweeps[0].update()
h3d.analyze(cores=NUM_CORES)
h3d = ansys.aedt.core.Hfss3dLayout()
touchstone_path = h3d.export_touchstone()  # Returns false.
