MBENDA$ is a Microstrip iCell and has no parameters. See “Intelligent Cells (iCells)” for more information.
Miter (M) is computed as a function of Angle and W/H.

This circuit component models an optimum Miter of an arbitrary angled bend in the Microstrip signal conductor. The model assumes a Quasi TEM mode of propagation matched to a Microstrip line of width (W) and incorporates the effects of dielectric and conductive losses. The basis of the model is a curve fit of experimentally determined optimum miters at specific angles within the specified range. At this time, the optimal miter percentage must be interpolated from the following table. The parameter W (Strip Width) is a dimension entered in the default length units. The parameter MSUB specifies the Microstrip Substrate element, which defines additional cross sectional parameters of the transmission line. M = 100 (x/d)

This element uses line types to determine its layout. By default, the layout uses the first line type defined in your Layout Process File (LPF). You can change the element to use any of the line types configured in your process:
-
Select the item in the layout.
-
Right-click and choose to display the Cell Options dialog box.
-
Click the Layout tab and select a Line Type.
-
Click to use the new line type in the layout.
See “Cell Options Dialog Box: Layout Tab ” for Cell Options dialog box Layout tab details.
See “The Layout Process File (LPF)” for more information on editing Layout Process Files (LPFs) and to learn about adding or editing line types.
Discontinuity models function most accurately when attached to lines that match their corresponding edges. Directly connecting discontinuity models to one another reduces their accuracy.
