A novel approach to analyzing and designing time problems of sequential circuits

Sequential circuit design technology is the base of digital circuit design such as programmable logic device and micro-controller interface. The sequential circuit design includes two basic problems: logic synthesis and time problems. Usually the digital circuit text introduces logic synthesis, but until now there is no systemic theory to study time problems. The following text would put forward a max-plus algebra based analyzing and designing method for time problems. This is a novel systemic theory to compute the time parameters of sequential circuit. In the end, a simple example would show the design process of the new method.
