Abstract
The present invention relates to a method for validating the correct logical function and timing behavior of a digital circuit design within a cycle-based verification environment. The method comprises the steps of providing a VHDL description of the digital circuit design, performing a logic synthesis, wherein the VHDL description is turned into a design implementation in terms of logic gates, and creating a netlist including the elements of the digital circuit design and the connections between said elements. The method comprises the further steps of providing a transformation script with at least one transparent storage element, wherein said transparent storage element represents a path delay within the digital circuit design, creating a new netlist with the at least one transparent storage elements, running a verification, and checking if the new netlist is clean from a logical and timing point of view.
