The invention relates to the technical field of data storage, and discloses an LPDDR5
digital signal capturing method based on a
logic analyzer, and the method comprises the steps: carrying out ball mounting
welding on CA signals and CS signals of A / B channels of LPDDR5 and to-be-tested instruments on a
test board, and selecting corresponding plots according to the actual connection condition, the number of the to-be-tested instruments being eight; during connection, Plot is distributed according to actually connected
signal lines, sampling clocks of each group of Plot are uniformly connected to a CKt / c
signal, impedance of an instrument to be tested is set according to
input impedance matching of a
logic analyzer, the LPDDR5 adopts a PODL level standard, and a
voltage threshold value of the instrument to be tested is set as VDDQ / 2; and a special protocol decoder of the LPDDR5 is loaded in
logic analyzer software. According to the invention, the problem of functional faults or performance bottlenecks existing in the final positioning digital
system is solved.
