expandable gate การใช้

• Third , it is that carries out a detailed and systematic study of the basic principles of cesd . the paper particularly makes the following extensions to cesd , such as or gate , “ n / k ” gate , expandable gate , feedback gate and renewable unit and transfer gate
• While in pratical applications , the esd method still has drawbacks in graphical modeling capability , connections with products " structures , size control of esd models , and etc . through in - depth study of the esd method , this paper systematically describes the framework and its basic modeling elements of esd , explains the principles of risk modeling , gives the mathematical model of the basic modeling elements of the esd framework to support the quantitative analysis of the esd model . based on the research above , this paper expands the esd framework , which includes : to overcome the drawback in graphic modeling capability of the esd method , the paper invents some new logical modeling symbols like " n / k " gate , sequence gate , expandable gate and constraint , those enrich the modeling capability of the esd method . to overcome the drawbacks in connections with products " structures and size control , the paper explains the multi - layered modeling principles based on the esd
