A simulation of a minicomputer controlled system and its use as a debugging tool
Yosuke Kobayashi · The Computer Journal · 1979
This paper establishes a general principle that all devices and computers embedded in a system should be considered equal from the viewpoint of the simulation design of a computer controlled system. This principle is a formal and general approach to simulation design especially for debugging aids and provides an excellent simulation technique offering generality, simplicity and flexibility. In addition a new, simple, and efficient time flow mechanism is presented. This mechanism can be widely applied to other kinds of programming whenever time management is necessary. For demonstrating and testing the new techniques, the simulation of a minicomputer system is implemented which is used for the purpose of developing and debugging real programs, especially those including input/output control instructions or sensitivity to input/output interrupt timing. This simulation technique can also be applied to a large computer system to debug programs or investigate its behaviour.
