Abstract: A node on a serial bus, preferably a device such as a personal computer (PC), can emulate other devices using virtual device drivers. A PC connected to a 1394 bus exposes its CROM on the bus which presents an image to other nodes on the 1394 bus and describes the functional units supported by the node. The CROM can be changed dynamically by adding unit directories to the CROM detailing peripherals connected to the PC. The PC can then be enumerated as the connected device by other PCs on the bus. The PC can emulate or morph itself into any desired device or even multiple devices at the same time. The invention also allows a PC to create devices that don't yet exist on the bus. The invention allows a user to create virtual device objects with device properties to have just in case a user plugs the particular device in to the PC.

Abstract: A virtual testbed for system verification test is provided in which emulated responses are associated with certain steps of a system verification test. The emulated responses can be manually entered or populated with previous test results obtained from execution of the emulation-enabled steps on a real testbed. When the emulation-enabled steps are executed, the system verification test uses the emulated responses as the responses corresponding to the actions of the emulation-enabled steps as if the steps were executed on the real testbed, without actually executing the emulation-enabled steps on the real testbed. Therefore, the virtual testbed of the present invention allows development of test scripts for system verification test without constant, actual access to the real testbed.

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.

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.

This invention resolves all ambiguities related to multiple triggers so that the user has a known predictable behavior based on the setup of the triggers.
