METHOD AND SYSTEMS FOR DETECTING AND ISOLATING HARDWARE TIMING CHANNELS

A method for detecting a timing channel in a hardware design includes synthesizing the hardware design to gate level. Gate level information flow tracing is applied to the gate level of the hardware design via a simulation to search for tainted flows. If a tainted flow is found, a limited number of traces are selected. An input on the limited number of traces is simulated to determine whether the traces are value preserving with respect to taint inputs, and to determine that a timing flow exists if the traces are value preserving with respect to the taint inputs.
