The invention discloses a surge measuring device and a surge measuring method. The surge measurement device includes a counting circuit system and a detection circuit system. The counting circuitry is coupled to the circuit under test. The counting circuit system is used to perform a first counting operation to generate a first counting signal according to an input signal sent to the circuit to be tested, and to perform a second counting operation to generate a second counting operation according to an output signal sent from the circuit to be tested. count signal. The detection circuit system is coupled to the circuit to be tested and the counting circuit system. The detecting circuit system is used for receiving the first counting signal and the second counting signal according to the input signal, and generating a surge indication signal according to the first counting signal and the second counting signal. The surge measurement device and surge measurement method provided in this case can be used to detect whether the operation of the circuit under test will generate surge by detecting the input signal and output signal of the circuit under test.
Description
technical field [0001] This case relates to a surge measuring device, and in particular relates to a surge measuring device and a surge measuring method that can utilize a counting circuit. Background technique [0002] In practical applications, electronic circuits are often disturbed by noise. These noises often come from many different sources. For example, when the delay time to be adjusted by the delay line circuit is too large, unnecessary glitches may be caused on the output signal of the delay line circuit, which may cause malfunctions in the operation of the electronic circuit or reduce the performance of the electronic circuit. Contents of the invention [0003] In order to solve the above problems, some aspects of the present application provide a surge measurement device, which is coupled to a circuit to be tested. The surge measurement device includes a counting circuit system and a detection circuit system. The counting circuit system is coupled to the cir...
