Switch Level Modeling
Designs at the logic level of abstraction, describe a digital circuit in terms of primitive logic functions such as OR, and NOR, etc., and allow for the nets interconnecting the logic functions to carry 0, 1, x and z values. At the analog-transistor level of modeling, we use an electronic model of the circuit elements and allow for analog values of voltages or currents to represent logic values on the interconnections.
