cumulativeViaGAR

Specifies the cumulative gate area ratio derived from the oacCumViaAntenna OpenAccess constraint.

Specifies the cumulative gate area ratio.

antennaAreaFactor (FltValue) specifies a factor, between 0 and 1, for calculating the antenna area. The default value is 1.
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.
