Abstract: A method and system for designing a structural level description of an electronic circuit with functional behavior described by a plurality of rules, the circuit being specified by data path and control path elements wherein at least one control path element is provided in a form of unresolved variable. The design comprises extracting a plurality of unresolved variables among the control path elements and automatic processing of data path and control path elements for accomplishing a state machine formulation, wherein the states of the state machine include states representing at least combinations of unresolved variables and corresponding transitions satisfying said plurality of rules and predefined design criteria.
