¶ A standard electrical via connect M2 (
top_layer
) to M1 (bottom_layer
) using a contact layer (via_layer
).The shape of each layer in the via is a regular polygon with a
n_o_sides
sides. and each layer element (top
,bottom
andvia
) is defined through the following properties:- top_process
- top_purpose
- top_width
analogous properties are defined for the other layers.
All those propeties can be overriden but they are defaulting to the values found in TECH.VIAS.VIA12
Parameters: bottom_process: ProcessLayer
Process of the
bottom
layer.bottom_purpose: PatternPurpose
Purpose of the
bottom
layer.bottom_width: float and number > 0
Width of the
bottom
layer (2 * inner radius of the polygon)n_o_sides: int and number > 0
Number of sides of the polygon used for the contact hole
top_process: ProcessLayer
Process of the
top
layer.top_purpose: PatternPurpose
Purpose of the
top
layer.top_width: float and number > 0
Width of the
top
layer (2 * inner radius of the polygon)via_process: ProcessLayer
Process of the
via
layer.via_purpose: PatternPurpose
Purpose of the
via
layer.via_width: float and number > 0
Width of the
via
layer (2 * inner radius of the polygon)view_name: str and ( Alphanumeric string or Contains _$ )
The name of the view
