Rethinking Embedded System Design

Embedded engineering is designed using objects of nature and it also interacts with nature.Therefore it is forced to obey the laws of nature. Nature does not make any assumptions. But allour mathematical and scientific theories do. Therefore these theories cannot be valid forembedded engineering applications. In this paper we present four new laws of nature that allembedded systems follow. These laws are (1) Boundedness (2) Finite time (3) Simultaneity and(4) Complexity. During the last fifty years embedded analog and digital engineering have evolvedand changed significantly. However our mathematical and scientific theories remained in theoriginal state. We select several theories commonly used in embedded engineering and showthat none of them satisfy these laws. As a result, when we implement these theories in ourembedded software, we are forced to add so many patches and kludges to make the engineeringwork, that our systems become very unreliable.
