Abstract
A parameterizable integrated circuit (IC) and method for designing, refining and implementing a circuit including the parameterizable IC are described. The method begins with receiving information on candidate sensing sub-circuits, parameterizable ICs and user specified requirements for the circuit including physical properties to be sensed and target values for the circuit. Each of the parameterizable ICs include a number of parametric analog and digital circuit elements, and a scheduler to schedule resources of the IC according to measurement priorities, measurement rates and the available circuit elements. Next, each of the candidate sensor-sub-circuits is evaluated with reference to the specified requirements, and each of the candidate ICs evaluated with reference to the requirements and the sensor-sub-circuits. Generally, the method further includes communicating to a user a number of candidate circuit-designs within a predetermined percentage of the one or more target values for the circuit.
