Abstract: A method for accelerating design space exploration of a target device when a behavioral description of the target device is given, includes: parsing the behavioral description to build a dependency parse tree; creating independent sets of clusters based on the dependency parse tree, each cluster being a set of a node or nodes of the dependency parse tree and independently explorable; exploring synthesizable operations of each cluster exhaustively in order to establish impact of each operation synthesized differently on a final circuit in designing of the target device; and combining attributes for the clusters to create designs with improved characteristics under constraints.

Abstract: A method for estimating power consumption of a target device upon designing the target device, includes: preparing a hybrid power library having a regression power library part and lookup-table power library part, the hybrid power library storing power characteristics for each of basic building blocks which will constitute the target device; and estimating power consumption of the target device by applying the hybrid power library to a design description of the target device.

Abstract: A method for automatically exploring a design space of an untimed high level language, comprising at least one of: (a) exploring automatically a set of local operations parsing an input source and assigning a set of attributes to each of the local operations; (b) exploring a set of global synthesis option that affects an entire design of a target circuit; and (c) exploring number and type of functional units allocated to the design.
