QDR-SRAM (Quad data rate-static random access memory) clock phase adjusting method and device

Abstract

The invention discloses a QDR-SRAM (quad data rate-static random access memory) clock phase adjusting method and device. The method is as follows: according to current phase and predetermined phase regulation rules of a QDR-SRAM clock, a phase adjustment signal of the QDR-SRAM clock can be generated, a received enable signal can be latched in the clock timing sequence of a received clock signal, the received phase adjustment signal can be latched in the latching period of the enable signal, and according to the phase adjustment signal, the current phase of the QDR-SRAM clock can be adjusted. According to automatic dynamic adjustment of the phase of the QDR-SRAM clock, the adjustment efficiency of the phase of the QDR-SRAM clock can be improved, phase debugging time and debugging error rate can be reduced, and fast, efficient and accurate clock phase adjustment can be achieved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a QDR-SRAM clock phase adjustment method and device. Background technique [0002] With the development of information technology, the operation speed of digital network equipment is getting faster and faster, and the complexity of the equipment is getting higher and higher, which also puts forward higher requirements for the performance of the equipment. For high-speed static random access memory (QDR-SRAM), because of its high-speed read-write frequency characteristics, it also has higher requirements for data read-write stability. In order to test the read-write Write stability, in the prior art, is mainly achieved by adding necessary constraints to QDR-SRAM and comprehensively debugging each phase point of the read and write clock of QDR-SRAM through a manual polling method. Determine the phase point that makes the QDR-SRAM stable, so as to test the stability of the QDR-SRAM, and si...
