Embodiment Construction

[0026] An embodiment of the present invention applied to the management of correction data of a 128M memory test bench will be described below.

[0027] Embodiment system management software, use the VMS system language of DEC company to carry out programming, its main function is: can realize the preservation of correction data, import, delete and generate relevant implementation resume, delete function has two kinds of forms of single and all for supplying Use it flexibly. The main features of the software are: dialogue mode, easy to operate; double confirmation is automatically implemented during program operation to prevent mistakes; main functions such as transfer are designed to be automatically implemented in the original program, reducing the amount of operation.

[0028] When the 128M memory test bench is testing, in order to manage the calibration data, all operations related to the calibration data must be considered. Figure 4 In the calibration data management pr...

Abstract

The present invention is one correcting data management system for test bench. The test includes the following process: initializing the test bench, calling program, correction, product test and completing test. The system features that correcting data call, save and delection program after calling program. The correcting data is saved before produced variation and called directly for test if needed, and this can save test time. After reaching its use term relevant technological condition specified, the correcting data is deleted to ensure product quality. The present invention raise the test efficiency of the test bench greatly.

Description

technical field [0001] The invention relates to the management of the calibration data of testing equipment, and is suitable for the data which has reusability and needs to be managed with valid period. Background technique [0002] When the high-precision test equipment is tested, the length of the test wiring from the test bench to the test point is different, which will cause the difference in signal transmission time and cause timing deviation. In order to eliminate the impact of deviation on the test, the test bench must measure the deviation of each test wiring and generate corresponding compensation data for time compensation during testing. This measurement process is called calibration, and the resulting compensation data is called calibration data. Calibration is generally carried out at the beginning of the test, and usually takes about 1 to 2 hours. The calibration results are stored in the dynamic memory in the form of data. When the test ...
