Embodiment Construction

[0085] refer to figure 1 , shows a modeling process known in the art, where different system components are specified at different levels of abstraction. The system model 1 is specified at a relatively high level by a programming language known as CY. Although the prior art and embodiments of the present invention are described using CY, alternative programming languages ​​may be used in a similar manner to those skilled in the art. Other components of the system are specified at lower abstraction layers. For example, two components are specified as Behavior Model 2 and Behavior Model 3 using System C and VHDL, respectively. Similarly, two additional components 4 and 5 are specified at RTL using VHDL and Verilog respectively. It should be understood that each programming language may be replaced by an alternative programming language.

[0086] figure 1 This includes a large number of models at different levels of abstraction. These models are simulated simultaneously. T...

Abstract

A method for modelling and simulating a system comprising first (X) and second (Y) interrelated components. The method comprises modelling the behaviour of said first (X) and second (Y) components using first and second specifications. Each of said first and second specifications includes a functional specification and an associated simulation element (82). The method further comprises simulatingthe behaviour of said first and second components using said first and second specifications. The simulation elements (82) communicate with one another to provide a simulation system.

Description

technical field [0001] The present invention relates to modeling and simulation methods. Background technique [0002] Build a model of the system and use the simulation process to verify that the behavior of the model under predetermined conditions is known. The system may comprise two or more interrelated components. Many modeling methods are known, and the particular method chosen is usually determined by the requirements of the system to be modeled. [0003] A specific application of modeling and simulation methods is to model and simulate computer hardware systems before constructing prototype systems. This is advantageous due to the time and expense involved in developing a prototype computer hardware system. Such modeling and simulation can substantially reduce the number of design iterations required before reaching a final design. In addition, modeling and simulation can increase the likelihood that the final system will operate as intended because it identifies...
