                      The disclosed invention relates to the field of data processing systems.                
                More particularly, the disclosed invention relates to the simulation of data                  
                processing systems including both a software component and a hardware                         
                component (Specification 2).                                                                  
                      Independent claim 1 is illustrative:                                                    
                      1.           A method of simulating a system having a software                          
                             component and a hardware component, said method comprising                       
                             the steps of:                                                                    
                                   (i) modelling operation of said software component using                   
                             a software simulator;                                                            
                                                                                                             
                                   (ii) modelling operation of said hardware component                        
                             using a hardware simulator;                                                      
                                   (iii) linking said hardware simulator and said software                    
                             simulator to model interaction between said modelled operation                   
                             of said hardware component and said modelled operation of                        
                             said software component;                                                         
                                   (iv) generating with a test controller, during said                        
                             modelling of software and hardware components and said                           
                             interaction, a software stimulus for said software component                     
                             and a hardware stimulus for said hardware component, said                        
                             software stimulus and said hardware stimulus are associated so                   
                             as to permit verification of correct interoperability of said                    
                             software component and said hardware component, wherein                          
                             said modelled interaction between said software component and                    
                             said hardware component proceeds independently of said test                      
                             controller;                                                                      
                                   (v) modelling the response of said software component to                   
                             said software stimulus; and
