[0022] In order to better illustrate the advantages of the system and method for dynamic testing of a digital system under test according to the present invention, first introduce other solutions.
[0023] In order to apply the traditional analog system dynamic test method to the bus-type digital system, the general digital system dynamic test method considers the use of signal conversion technology to achieve mutual conversion between analog signals and digital bus signals. The analog signal conversion digital bus signal is hereinafter referred to as A / D, and the digital bus signal conversion analog signal is hereinafter referred to as D / A.
[0024] In the general bus-type digital system dynamic test method, the signal from the signal generating device and the signal after the D / A conversion of the tested digital system feedback signal are input to the analysis device to compare and analyze the dynamic characteristics of the system. This method has major drawbacks. The added signa...
