This reset signal is provided by the device (eg, the power output stage control unit). PCI-E uses this signal to reset the internal logic. When the signal is valid, the PCI-E slot and its associated devices will be reset. Fifth, a wake-up signal (Wake up), when the PCI-E device enters the sleep state and the main power supply has stopped supplying power, the PCI-E device uses the Wake up signal to send a wake-up request to the processor system, so that the processor system is re-enabled.

The above six functions can make this verification system more perfect, so that the user can be more comfortable on the verification device. It can be noted that although these six functions are provided on the high-speed bus device, the operation can be regarded as actual operation. Users need to reduce several of these features to reduce their system cost; or add other features to the system that are acceptable.

In the above specific embodiments, the input and output modules, the power output stage control system, and the plurality of PWM modules are combined with other necessary components to provide various voltages of the verification terminal device to simulate different commercial products. The power supply, the different forms of voltage generated, such as the power on timing and voltage level are different. Therefore, the present invention can provide a voltage-related test with a complete verification end.

And because information products are changing with each passing day, it is often the case that multiple products are in the sample design stage at the same time, and each sample design must use various forms of voltage testing as much as possible to shorten the time to market. Although the present invention has been described above by taking one or two system devices as an example, it should be noted that the present invention is not limited thereto. In other words, the method of the present invention can provide multiple sets of verification devices Multiple sets of sample designs allow for more than one set of sample design execution validations. As a result, the time to market and the cost of production can be greatly reduced.
