The invention discloses a
satellite load
data simulation source testing method and device. The method comprises the steps of: receiving a testing instruction, and generating and transmitting a pseudo-random
data simulation source; receiving the pseudo-random
data simulation source, generating a comparison template in real time, comparing the comparison template with filling data in real time, andjudging whether the filling data has an error code or not; verifying the frame header information and the
data filling, generating a comparison template for
verification filling, comparing the comparison template for
verification filling with the
verification filling in the pseudo-random data
simulation source, and judging whether the whole data frame has an error code or not; and caching the frame header information of a plurality of channels for the condition that the frame header information part has an error code or may have an error code, performing grouping sorting on the frame header information according to the
virtual channel identifier, judging whether the frame header information part has an error code or not again, determining an error code position, and obtaining error code related information. According to the invention, real-time online interpretation of data can be realized, not only are storage resources of a test
system saved, but also the
test efficiency of a
solid-state memory is improved.
