Abstract

The invention relates to a VI source measurement data acquisition and display method. The deficiencies of the prior art are solved. The technical solution is applicable to a PC end configured with a PCI_E high-speed interface card. The PC end is connected with the FPGA chip through the PCI_E high-speed interface card. The FPGA chip acquires the VI source measurement data of a hardware resource board card through an AD sampling circuit. The method comprises the steps that 1 the FPGA chip transmits data collected by the AD sampling circuit to the PC end through the PCI_E high-speed interface card; and 2 the PC end processes the data in a graphical manner for display, and a visual operation mode is provided for a user to view analysis data.

Description

technical field [0001] The invention relates to the technical field of semiconductor testing, in particular to a method for collecting and displaying VI source measurement data. Background technique [0002] In the field of semiconductor testing, for the measurement of a circuit under a certain condition, most manufacturers' solutions are to perform multiple measurements under the same conditions, and sample these test results, and then calculate and process these test results according to a specific algorithm. The calculated value is taken as the data result of this measurement of the test system. [0003] The above-mentioned final measurement results will be provided to users to view, use and save in different ways for each testing machine. However, there are still many deficiencies in saving and displaying the original data obtained by multiple sampling before the algorithm processing. [0004] If it is necessary to view the intermediate process of measurement, each man...
