Circuit: automatic report creation#

This example shows how you can use PyAEDT to create reports automatically using a JSON file.

Perform required imports#

Perform required imports and set the local path to the path for PyAEDT.

# sphinx_gallery_thumbnail_path = 'Resources/spectrum_plot.png'
import os

import shutil
from pyaedt import examples
from pyaedt import generate_unique_folder_name

import tempfile

# Set local path to path for PyAEDT
temp_folder = generate_unique_folder_name()
project_path = examples.download_custom_reports(temp_folder)

Import main classes#

Import the main classes that are needed: pyaedt.Desktop and pyaedt.Circuit.

from pyaedt import Circuit
from pyaedt.generic.DataHandlers import json_to_dict

Launch AEDT#

Launch AEDT 2022 R2 in graphical mode. This example uses SI units.

desktopVersion = "2022.2"

Set non-graphical mode#

Set non-graphical mode. "PYAEDT_NON_GRAPHICAL"` is needed to generate documentation only. You can set non_graphical either to True or False. The Boolean parameter new_thread defines whether to create a new instance of AEDT or try to connect to an existing instance of it.

non_graphical = os.getenv("PYAEDT_NON_GRAPHICAL", "False").lower() in ("true", "1", "t")
NewThread = True

Launch AEDT with Circuit#

Launch AEDT with Circuit. The pyaedt.Desktop class initializes AEDT and starts the specified version in the specified mode.

cir = Circuit(projectname=os.path.join(project_path, 'CISPR25_Radiated_Emissions_Example22R1.aedtz'), non_graphical=non_graphical,

Create spectrum report#

Create a spectrum report. You can use a JSON file to create a simple setup or a fully customized one. The following code creates a simple setup and changes the JSON file to customize it. In a spectrum report, you can add limitilines and notes and edit axes, the grid, and the legend. You can create custom reports in non-graphical mode in AEDT 2022 R2 and later.

report1 =,'Spectrum_CISPR_Basic.json'))

if not non_graphical:
    report1_full =,'Spectrum_CISPR_Custom.json'))

Create transient report#

Create a transient report. You can read and modify the JSON file before running the script. The following code modifies the traces before generating the report. You can create custom reports in non-graphical mode in AEDT 2022 R2 and later.

if non_graphical:
    props = json_to_dict(os.path.join(project_path, 'Transient_CISPR_Basic.json'))
    props = json_to_dict(os.path.join(project_path, 'Transient_CISPR_Custom.json'))

report2 =, solution_name="NexximTransient")
props["expressions"] = {"V(Battery)": {}, "V(U1_VDD)": {}}
props["plot_name"] = "Battery Voltage"
report3 =, solution_name="NexximTransient")

Create eye diagram#

Create an eye diagram. If the JSON file contains an eye mask, you can create an eye diagram and fully customize it. You can create custom reports in non-graphical mode in AEDT 2022 R2 and later.

report4 =,'EyeDiagram_CISPR_Basic.json'))

if not non_graphical:
    report4_full =,'EyeDiagram_CISPR_Custom.json'))

if not non_graphical:, report4.plot_name)

Save project and close AEDT#

Save the project and close AEDT.

print("Project Saved in {}".format(cir.project_path))
Project Saved in D:/Temp/PyAEDTExamples/custom_reports/
