Accurate system level models of rf circuits

A method for simulating the behaviour of the rf sections of communications systems hardware allows accurate implementation-dependent models to be introduced into system-level simulation. Accuracy of modelling of typical sub-systems is shown to be very close to transistor-level circuit analysis, but computational speed can be orders of magnitude greater. Accuracy is achieved by extracting parameters from transistor-level circuit designs. These models have been added to an existing system level simulator TraSim. The extended simulator, CLASS (Circuit Level Accuracy System Simulator), is integrated into the Cadence Analogue Artist CAD environment
