  • Patent number: 8676560
    Abstract: In a normal operation, a physical unit simulator is allowed to speculatively perform high-speed continuous execution. Only when an actual input comes in, a speculative input and the actual input are compared with each other. Thereafter, in response to inconsistency between the inputs, the physical unit simulator is returned to a point closest to the point of the actual input and is allowed to execute a variable step module to reach the point of the actual input. Upon arrival at the point of the actual input, the simulator is shifted back to the high-speed continuous execution from there. Thus, a processing speed of the simulator can be significantly improved.

  • Publication number: 20140025365
    Abstract: System and method for achieving reproducibility of a simulation operation while reasonably keeping an operation speed. A peripheral scheduler clears completion flags of all the peripheral emulators to thereby start parallel operations thereof. Then, based on processing break timing set for the individual peripheral emulators, the peripheral scheduler finds one of the peripheral emulators which is scheduled to reach a processing break at the earliest. The found peripheral emulator is referred to as a peripheral P. In a case where a time of the processing break of the peripheral P is T, the peripheral scheduler continues execution of processor emulators and plant simulators up until a time point of the time T. The peripheral scheduler waits for setting of a completion flag of the peripheral P. In response to the setting, the peripheral scheduler performs data synchronization among the peripheral P, the processor emulators, and the plant simulators.

    Abstract: An access monitoring section (11) obtains access information including an address conforming to an address stored in a monitoring address setting section (10) from an access signal output from a CPU (1) to a peripheral device (3). An access judging section (13) compares the access information received from the access monitoring section (11) and the last access information stored in an access storing section (12), and stores the obtained access information in the access storing section (12) and requests the transmission of an exception generation notification to an exception generating section (14) when the received access information is different from the last access information while excluding the last access information stored in the access storing section (12) from access information to be compared when the received access information is the same as the last access information. By this construction, throughput can be reduced at the time of emulation and the peripheral device can be efficiently emulated.
