I would like to measure the power consumption of a circuit, such as an inverter.
The version of Hspice I used is 2012.06-SP2 64-BIT.
The version of BSIM-CMG I used is BSIMCMG106.0.0.
The Hspice file is as follows :
The power consumption reported by Hspice is 0.
Obviously, the power consumption reported by Hspice is wrong.
Does anyone know the correct way to measure the power consumption of a circuit with Hspice using BSIM-CMG ?
