BoolValue

Specifies whether the antenna constraints represent the side area or the drawn top surface area.

Parameters

• antennaAreaFactor (FltValue) specifies a factor, between 0 and 1, for calculating the antenna area. The default value is 1.
• antennaCumRoutingPlusCut (BoolValue) indicates whether the cumulative antenna ratio of the layer immediately below or the like layer immediately below for a layer’s cumulative antenna calculation is included.
• antennaDiffAreaReduceFactor (Flt1DTblValue) multiplies the conductor area by a floating point factor that depends on the diffusion area attached to the net. If the antennaDiffMinusFactor is non-zero, the subtraction of the diffusion area times the antennaDiffMinusFactor must occur after the metal and cut areas are multiplied by the antennaDiffAreaReduceFactor.
• antennaDiffPlusFactor (FltValue) determines how the diffusion area connected to the net is added to the area of the gate for antenna/gate ratio calculations. The default value is 0.0.
• antennaDiffMinusFactor (FltValue) determines how the diffusion area connected to the net is subtracted from the antenna area when calculating antenna/gate ratio for both metal and cut layers.
