Title:
SIMULATION METHOD, SYSTEM, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2010/104135
Kind Code:
A1
Abstract:
In a simulation system, the operation speed of the simulation system is improved by reducing the communication cost between a continuous series system and a discrete series system. At least some of the peripherals of ECU emulators serving as the discrete series system are separated so as to be operated by the thread of the continuous series system. In addition, the continuous series system and the peripherals sparsely communicate with each other because of performing a loose synchronization. With the configuration, the frequency of the thread-to-thread communication between the continuous series system and the discrete series system is significantly reduced in response to a continuous clock in the simulation system configured from the continuous series system and the discrete series system, resulting in reduced communication cost. As a result, the operation speed of the simulation system can be improved.
