Abstract
A system and method are provided for selectively inferring latch elements in a circuit design from an event-driven hardware description language (HDL) file to an event-independent format. The method includes modeling the file as a plurality of data flow equations, analyzing the plurality of equations for uninitialized variables, and placing a latch at any utilized, uninitialized variable. Control signal information for an inferred latch is also derived during the data flow analysis.
