Circuit: schematic subcircuit management

This example shows how you can use PyAEDT to add a subcircuit to a circuit design. It pushes down the child subcircuit and pops up to the parent design.

Perform required import

Perform the required import.

import os
import pyaedt

Set AEDT version

Set AEDT version.

aedt_version = "2024.1"

Set non-graphical mode

Set non-graphical mode. You can set non_graphical either to True or False.

non_graphical = False

Launch AEDT with Circuit

Launch AEDT 2023 R2 in graphical mode with Circuit.

circuit = pyaedt.Circuit(projectname=pyaedt.generate_unique_project_name(),
                         specified_version=aedt_version,
                         non_graphical=non_graphical,
                         new_desktop_session=True
                         )
circuit.modeler.schematic_units = "mil"

Add subcircuit

Add a new subcircuit to the previously created circuit design, creating a child circuit. Push this child circuit down into the child subcircuit.

subcircuit = circuit.modeler.schematic.create_subcircuit(location=[0.0, 0.0])
subcircuit_name = subcircuit.composed_name
circuit.push_down(subcircuit)

True

Parametrize subcircuit

Parametrize the subcircuit and add a resistor, inductor, and a capacitor with the parameter values in the following code example. Connect them in series and then use the pop_up # method to get back to the parent design.

circuit.variable_manager.set_variable(variable_name="R_val", expression="35ohm")
circuit.variable_manager.set_variable(variable_name="L_val", expression="1e-7H")
circuit.variable_manager.set_variable(variable_name="C_val", expression="5e-10F")
p1 = circuit.modeler.schematic.create_interface_port(name="In")
r1 = circuit.modeler.schematic.create_resistor(value="R_val")
l1 = circuit.modeler.schematic.create_inductor(value="L_val")
c1 = circuit.modeler.schematic.create_capacitor(value="C_val")
p2 = circuit.modeler.schematic.create_interface_port(name="Out")
circuit.modeler.schematic.connect_components_in_series(assignment=[p1, r1, l1, c1, p2], use_wire=True)
circuit.pop_up()

True

Release AEDT

Release AEDT.

circuit.release_desktop(True, True)

True
