    摘要: A technique for enhancing the execution efficiency of simulation of a hybrid system. A continuous system simulator receives a request for evaluation of an event generating conditional expression for an event to be processed by a discrete system simulator, from the discrete system simulator. The event generating conditional expression is evaluated by referring to the value of a first variable describing a continuous system. Until evaluation of the event generating conditional expression indicates true, the continuous system simulator repeats simulation of advancing the current time by a step time interval and evaluation of the event generating conditional expression. When evaluation of the event generating conditional expression indicates true, the continuous system simulator sends current time data and the value of a second variable describing the continuous system which is referred to by the discrete simulator, to the discrete simulator.

    摘要: A system, method and computer program for generating a sequence diagram that specifies processing among modules included in source code. First, a source code is acquired and then analyzed to generate a log acquisition code for acquiring an execution log. Then, a program including the generated log acquisition code is executed to acquire execution log information on the execution of the program. On the basis of the acquired execution log information, automaton information on states and transitions among the states is extracted, and then the extracted automaton information is converted into sequence diagram component information on components constituting a sequence diagram. Thereafter, a sequence diagram is generated based on the converted sequence diagram component information.
