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.

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

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.

temp_folder = tempfile.TemporaryDirectory(suffix=".ansys")

Download example data

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.

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.

Create virtual compliance report

Initialize the VirtualCompliance class and set up the main project information needed to generate the report.

template = os.path.join(download_folder, "pcie_gen5_templates", "main.json")

v = VirtualCompliance(circuit.desktop_class, str(template))

Customize project and design

Define the path to the project file and the design names to be used in each report generation.

v.project_file = circuit.project_file
v.reports["insertion losses"].design_name = "LNA"
v.reports["return losses"].design_name = "LNA"
v.reports["common mode return losses"].design_name = "LNA"
v.reports["tdr from circuit"].design_name = "TDR"
v.reports["eye1"].design_name = "AMI"
v.reports["eye3"].design_name = "AMI"
v.parameters["erl"].design_name = "LNA"
v.specs_folder = os.path.join(download_folder, "readme_pictures")

Define trace names

Change the trace name with projects and users. Reuse the compliance template and update traces accordingly.

v.reports["insertion losses"].traces = insertion

v.reports["return losses"].traces = return_diff

v.reports["common mode return losses"].traces = return_comm

v.reports["eye1"].traces = eye_curve_tx
v.reports["eye3"].traces = eye_curve_tx
v.reports["tdr from circuit"].traces = tdr_probe_name
v.parameters["erl"].trace_pins = [
    [
        "X1.A5.PCIe_Gen4_RX1_P",
        "X1.A6.PCIe_Gen4_RX1_N",
        "U1.AR25.PCIe_Gen4_RX1_P",
