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 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.

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

Launch AEDT with Circuit#

Launch AEDT 2022 R2 in graphical mode with Circuit.

circuit = pyaedt.Circuit(projectname=pyaedt.generate_unique_project_name(),
                         specified_version="2022.2",
                         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(components_to_connect=[p1, r1, l1, c1, p2], use_wire=True)
circuit.pop_up()
True

Duplicate subcircuit#

Duplicate the previously created subcircuit and set a new parameter value. This works only in graphical mode.

if not non_graphical:
    new_comp = circuit.modeler.schematic.duplicate(component=subcircuit_name, location=[200, 0])
    new_comp.parameters["R_val"] = "75ohm"

Release AEDT#

Release AEDT.

circuit.release_desktop(True, True)
True
