Incremental behavioral simulations on a network of transputers

Authors: Dimond, Keith, Hassan, Samir

Abstract:

Simulation plays an important role in the design process for modern digital and analogue systems. There are many different types of simulators capable of representing the behaviour of the system at a number of different levels of abstraction. Because of its vital importance there is an ever increasing need to enhance the performance of simulators. Enhancements can occur in many different aspects. These may be in the speed of simulation, or in the accuracy of modelling. This paper describes a relatively new enhancement that of incremental operation which has the advantage of allowing the simulator to respond very rapidly to design changes in addition to providing an enhanced rate of simulation.The simulator which is described in this paper operates at the behavioural level. This allows the designer to specify, using suitable code segments descriptions of the behaviour of the functional blocks which make up the design. This approach may be used to model a digital system at the gate level, where signal values correspond to standard logic levels. In addition this mode of simulation has the attraction of being able to model very complex blocks which might very well have inputs and outputs which are most conveniently represented by complex data structures. This simulator is able therefore to model a complete system, some parts represented at this nigh-level of abstraction whilst other parts may be modelled at the lower levels of abstraction where greater detail is required.
