Trace#

class pyaedt.modeler.advanced_cad.stackup_3d.Trace(application, frequency, line_width, line_impedance, signal_layer, dielectric_layer, line_electrical_length=90, line_length=None, line_position_x=0, line_position_y=0, line_name='line', reference_system=None, axis='X')[source]#

Trace Class in Stackup3D. Create a parametrized trace. It is preferable to use the add_trace method in the class Layer3D than directly the class constructor.

Parameters:

applicationpyaedt.hfss.Hfss: HFSS design or project where the variable is to be created.
frequencyfloat, None: The line frequency, it is used in prediction formulas. If it is None, the line frequency will be that of the layer or of the stackup.
line_widthfloat, None: The line width. If it is None, it will calculate it from characteristic impedance of the line.
line_impedancefloat: The characteristic impedance of the line. If a line width is entered by the user, the characteristic impedance will be calculated from it.
signal_layerpyaedt.modeler.stackup_3d.Layer3D: The signal layer where the line will be drawn.
dielectric_layerpyaedt.modeler.stackup_3d.Layer3D: The dielectric layer between the line and the ground layer. Its permittivity and thickness are used in prediction formulas.
line_electrical_lengthfloat, None, optional: The ratio between the line length and the wavelength in degree. By default 90 which is corresponding to the quarter of the wavelength. If it is None, it will be directly calculated from the line length entered by the user.
line_lengthfloat, None, optional: The line length. By default, it is None and so the length is calculated by prediction formulas according to the electrical length.
line_position_xfloat, optional: Line x position, by default it is 0.
line_position_yfloat, optional: Line y position, by default it is 0.
line_namestr, optional: Line name, by default “line”.
reference_systemstr, None, optional: Coordinate system of the line. By default, None.
axisstr, optional: Line length axis, by default “X”.

Examples

>>> from pyaedt import Hfss
>>> from pyaedt.modeler.stackup_3d import Stackup3D
>>> hfss = Hfss(new_desktop_session=True)
>>> my_stackup = Stackup3D(hfss, 2.5e9)
>>> gnd = my_stackup.add_ground_layer("gnd")
>>> my_stackup.add_dielectric_layer("diel1", thickness=1.5, material="Duroid (tm)")
>>> top = my_stackup.add_signal_layer("top")
>>> my_trace = top.add_trace(line_width=2.5, line_length=22)
>>> my_stackup.resize_around_element(my_trace)
