Abstract: An apparatus is provided for programming a programmable circuit device capable of realizing at least one sub-circuit by wiring together at least one circuit component. The programmable circuit device includes a programmable computing device, a user interface, and a design tool. The user interface is associated with the programmable computing device. The design tool is associated with the programmable computing device and is configured for interaction with a user at the user interface. The design tool includes computer program code embodied in the programmable computing device including a sub-circuit definition containing information for defining at least one of multiple configurations, topologies, and parameters of a sub-circuit of a programmable device. A method is also provided.

Abstract: An apparatus is provided for simulating switched-capacitor circuits. The apparatus includes a programmable computing device, a design tool, and a behavioral simulator. The design tool is associated with the programmable computing device and is configured for interaction with a user. The design tool includes a sub-circuit definition for defining a sub-circuit of a programmable circuit device. The behavioral simulator is associated with the design tool. The behavioral simulator is configured to represent each sub-circuit via a set of discrete time-domain equations giving output of the sub-circuit as a function of input to the sub-circuit. A method is also provided.

Abstract: A method comprising providing an interpretable coded algorithm; providing an executable coded algorithm; determining whether the interpretable coded algorithm is functionally equivalent to the executable coded algorithm; and selectively performing one of interpreting the interpretable coded algorithm and executing the executable coded algorithm.
