Depending on schedulability problem of the complex real-time system including periodic tasks in multi-processor and multi-partition structure,this paper proposes a tool based on simulation method of schedulability in the task set.Through the setting of clock variables,the tool can simulate task scheduling process,determine the simulation interval according to the characteristics of periodic task set,and optimize the algorithm to determine the schedulability.Test results and analysis verify that this tool has automatic,accurate and fast advantages to describe task scheduling process by Gantt chart.Compared with the other existing tools,it is more accurate and efficient.
