On the race-free and minimal cost coding of the internal states in computer aided design of sequential switching systems: On the programming system RENDIS-s for the design of sequential switching systems

A number of properties of a sequential switching system depend on the coding of the internal states. The coding, for example, has an effect on the logic element requirements, the speed of switching, and the memory requirements. Unclocked sequential switching networks may, in addition, exhibit so-called race conditions which result in faulty operation of the network. These race conditions are attributable to the non-ideal transition behavior of real components. The coding procedure described in the report was principally devised for the computer-aided design of industrial controls.
