Description

BACKGROUND OF THE INVENTION This application claims priority for the TW patent application No. 113101214 filed on 11 Jan. 2024, the content of which is incorporated by reference in its entirely. FIELD OF THE INVENTION The present invention relates to a system and a method for analyzing data in an electrostatic discharge testing field, particularly to analysis for transmission line pulse (TLP) data. DESCRIPTION OF THE RELATED ART In the existing technology, electrostatic discharge (ESD) testing is another method commonly used to evaluate the performance of protection components. For example, the protection component is a transient voltage suppressor. ESD testing simulates real-world electrostatic charging events, such as human body model (HBM) testing, to determine the response and effectiveness of protective components in such events. However, ESD testing also has some shortcomings. For example, it may not provide sufficient information to completely describe all important characteristics of protection components and may ignore some key performance indicators, such as clamping voltage and leakage current. In order to determine the characteristics of the protection components, those skilled in the art will further use transmission line pulse (TLP) testing. The traditional TLP testing method can only measure the response of protection components within a constant time period and a required current capability. This makes it difficult for those skilled in the art to obtain comprehensive and accurate information about protection components in different application scenarios and environmental conditions. For example, traditional TLP testing may not be able to simulate long-term low-current applications or high-frequency current pulse events. In addition, traditional TLP testing methods may ignore the performance changes of protection components in different environmental conditions (such as different temperature and humidity conditions). In addition, traditional TLP testing methods usually require a lot of manual operations and human resources. For example, those skilled in the art may need to manually configure testing equipment and make ongoing monitoring and adjustments during a testing process. This not only increases the time and cost of testing, but also increases the risk of errors during the testing process. Therefore, based on the existing technology, traditional ESD testing and TLP testing methods have many limitations and deficiencies in determining the complete characteristics of protection components. These deficiencies limit those skilled in the art from completely understanding the performance of protection components, thereby affecting the selection and application of protection components, which may cause poor protection of electronic devices in transient voltage events. This emphasizes the importance and urgency of developing a new, more comprehensive and more effective method for analysis and processing of protection components to meet the needs of different applications and environments and to improve the protection effectiveness of electronic devices. SUMMARY OF THE INVENTION In order to achieve the foregoing objectives, the present invention provides a method for processing transmission line pulse data, which is performed by a processing device to determine whether the component characteristic of at least one protection component meets a design window. The method includes: obtaining the transmission line pulse data that includes a voltage-current characteristic generated by applying transmission pulses to the at least one protection component; determining the component characteristic of the at least one protection component based on the voltage-current characteristic; obtaining the design window; determining whether the component characteristic of the at least one protection component meets the design window to obtain a determination result; and generating a visual graph with the design window, the determination result, and the voltage-current characteristic. In an embodiment, the design window is configured to determine the operating range and the safe range of a protected electronic component. In an embodiment, the transmission line pulse data further include electric leakage information. The electric leakage information includes electric leakage values generated by applying different the transmission pulses to the protection component. The step of determining the component characteristic of the protection component includes: based on a given component breakdown condition, determining whether the electric leakage values of the electric leakage information are greater than a current threshold value of the component breakdown condition; when the electric leakage value meets the component breakdown condition, respectively configuring a current and a voltage corresponding to the electric leakage value (i.e., the last electric leakage value before the breakdown of the protection component) clos
