R = averaging time in seconds
M = parameterized memory space in megabytes (MByte)
A = number of VCDAUs activated in the device with star/delta parameterization
B = number of VCDAUs activated in the device with monophase parameterization plus the
coupled CDAUs with star/delta parameterization
C = number of CDAUs activated in the device with monophase parameterization
