Popis: Many embedded controllers have some critical system states that depend on an asynchronous event. Currently handling them in design depends on the availability of always-on slow clocks. In this paper we present a generic asynchronous design scheme that doesn't require a clock and ensure a reliable functionality without associated deadlock scenariossensitive to exact arrival times of asynchronous events. This is enabled by a novel pulse width insensitive design method, which also requires unconventional verification methodology that ensures thorough and comprehensive pre-silicon design quality. These have been applied on the latest, ultra-low cost embedded micro-controller design targeted for cost sensitiveapplications.
