d_dbViaId	Database ID of a via.
t_dbViaLayerType	Name of a valid via layer type. Valid values: layer1, layer2, cutLayer
t_colorControl	Color control that can be assigned to the specified layer in the given via. Valid values: noColor, noShift, shift1, and so on, up to shiftx, where x is an integer equal to (number of masks for the via layer - 1).

nil	The operation failed.

Example

In this example, the following color controls are assigned to the specified layers in the via via1t_m2_m1:

• Color control shift2 to the layer layer2.
• Color control shift1 to the layer layer1.
• Color control shift1 to the layer cutLayer.

cv = dbOpenCellViewByType("tech" "design" "layout" "maskLayout" "w")

viaDef_M2_M1 = techFindViaDefByName(tf "M2_M1")

via1t_m2_m1 = dbCreateVia(cv viaDef_M2_M1 10:10 "R0")

dbSetViaLayerControl(via1t_m2_m1 "layer2" "shift2")

=> t

dbSetViaLayerControl(via1t_m2_m1 "layer1" "shift1")

=> t

dbSetViaLayerControl(via1t_m2_m1 "cutLayer" "shift1")

=> t
