Abstract

An environment and method are provided for designing and implementing a circuit comprising an integrated circuit (IC) including a number of parametric analog elements for which operating parameters can be set. Generally, the method comprises: specifying requirements for the circuit including physical properties to be sensed by the circuit and actions to be taken by the circuit; designing the circuit based on the specified requirements and resources available on the IC; and setting parameters of at least one of the parametric analog circuit elements of the IC based on the circuit design. In one embodiment, the specifying, designing, and setting parameters steps are performed using a computer executable code embodied in a computer readable medium on a server coupled to a client computer through an internet protocol network. Other embodiments are also provided.
