Embodiment Construction

[0040] see figure 1 , The QDR SRAM application verification system of the present invention includes a PC, a QDR SRAM application verification board and a program-controlled power supply.

[0041] QDR SRAM application verification board includes FPGA, serial port module, power module, controllable power module, current detection module, JTAG and QDR SRAM under test

[0042]The FPGA integrates a QDR SRAM controller and a controllable clock unit. The QDR SRAM controller is used to connect the tested QDR SRAM. The QDR SRAM controller sends control signals, addresses and input data to the tested QDR SRAM according to the received PC verification instructions. Collect the output data of the tested QDR SRAM; the controllable clock unit is the internal PLL of the FPGA, which is used to generate two clock frequencies, the first clock frequency is used for the normal operation of the FPGA, and the second clock frequency is used as the input of the tested QDR SRAM Clock frequency; veri...

Abstract

The invention discloses a QDR SRAM application verification system, which comprises a PC (Personal Computer), a QDRSRAM application verification board and a programmable power supply, and realizes comprehensive verification of various functions of a tested QDR SRAM circuit. The invention also discloses a verification method based on the system. The method comprises the steps: firstly determining a power-on sequence, and then carrying out read-write function application verification, JTAG function application verification and I/O current characteristic application verification. The verification function is comprehensive, the universality is high, and the method has important significance on application verification of the QDR SRAM.

Description

technical field [0001] The invention belongs to the field of chip application verification, and relates to a QDR SRAM application verification system and a verification method thereof. Background technique [0002] At present, domestic manufacturers who design and produce QDR SRAM for aerospace are mostly in their infancy, and have little experience in QDR SRAM application verification. Most of them use verification systems and verification methods to verify the timing matching between QDR SRAM controller and QDRSRAM. First, The verification items for QDR SRAM are not sufficient, and are not compatible with different types of QDR SRAM. The second verification method is relatively single and not universal. For this reason, it is necessary to develop a QDR SRAM application verification system and its verification method to meet the application verification requirements of QDR SRAM. Contents of the invention [0003] The problem solved by the technology of the present invent...
