Abstract:
In this paper we evaluate a promising delay estimation method, the Involution Delay Model. We apply it to three simple circuits (a combinatorial loop, an SR latch and an adder), interpret the delivered results and determine realistic overhead estimations. Comparisons to analog SPICE simulations reveal fine-grained behavioral coverage, whereat the commonly used digital inertial delay model shows severe shortcomings. Overall, the Involution Delay Model is able to identify a wide range of malicious behavior and is thus a viable upgrade to available delay models in modern digital timing simulation tools.
