Abstract

MANY PUBLISHED efforts in the field of logical simulation indicate that the programming concept of “compiling and executing” is the most frequently used foundation for the construction of simulation programs. The technique to be described here represents a complete departure from the concept of “compiling and executing”. The basic framework for the simulation method to be presented is simply a close imitation of the structure and operation of a logical network. Applying this concept leads to a realistically operating “general purpose” simulator. The resulting simulation possibilities are—at least with respect to the field of logical simulation—relatively unexplored and unexploited. Simulation in other fields, e.g., the simulation of nerve nets by Reiss1, has preceded the field of logical simulation in taking advantage of the structure and operation of (neural) networks. The first success in applying these methods to the field of logical simulation has been reported by Case, et al2.
