You may want to look up asynchronous logic - it's more complicated that you realize. In fact, you'll quickly understand why 99% of all digital designs use synchronous logic design instead - it has a far smaller gate count to accomplish the same function. There are legitimate places where asynchronous logic can be very useful: specifically when you are interacting with the "real world" which is not synchronous. But once you get beyond that, going back to synchronous design is usually best. http://www2.imm.dtu.dk/pubdb/edoc/imm855.pdf http://www2.imm.dtu.dk/pubdb/edoc/imm855.pdf https://www.researchgate.net/publication/245530456_Asynchronous_Circuit_Design_Motivation_Background_Methods https://www.researchgate.net/publication/245530456_Asynchron... https://www.researchgate.net/publication/331181568_Asynchronous_Design_--_Part_2_Systems_and_Methodologies https://www.researchgate.net/publication/331181568_Asynchron...
