Its output information is too much 伽 analysis. Taking one of the models in the Modeler tutorials and several debugging missions for instances. the normal methods for ob自erving collisions in bus link through built叮1 statistics，恤cin岳阳haviors of a m叫ule or proces8 and monitoring vari咄 ahles under OOB are íntroduced. A more convenient and simple method is proposed , which exploits mainly the op_sim_me唱­ sage keroel procedur队The OUtput information is simplified and completely held in the simulation window thus it can easily be handled with Microsoft Word. Through the same example, how to investigate bus collision deta伽， monitor variahles , and test 由.e program 8 logic is demonstrated. Key codes, notes and information deali吨 steps are also presented.
