Abstract:
1. A computer system for testing a characteristic impedance of a signal path routing of a printed circuit board (PCB), the computer system comprising: a storage; at least one processor; and one or more programs stored in the storage and being executable by the at least one processor, the one or more programs comprising: a receiving module operable to receive test information; an initialization module operable to initialize a test device connected to the computer system; an obtaining module operable to obtain status parameters of the test device, obtain test parameters of the signal path routing of the PCB according to the test information if the status parameters of the test device are valid, and store the test parameters of the signal path routing of the PCB in the storage; a test module operable to control the test device to test a characteristic impedance of the signal path routing of the PCB according to the test parameters, obtain test data of the signal path routing of the PCB from the test device, and store the test data of the signal path routing of the PCB in the storage; an analysis module operable to compare the test data of the signal path routing of the PCB with a corresponding standard characteristic impedance in the test parameters, and determine if the test data of the signal path routing of the PCB is acceptable; a generation module operable to generate a test report to store the test data of each signal path routing of the PCB and corresponding comparison result if all signal path routings of the PCB have been tested, and store the test report in the storage.
