Problems solved by technology

However, the input of ERROR through the chip pins will occupy bus resources, and the timing of ERROR injection cannot be accurately controlled. If the data in the memory itself has errors and is corrected after passing through the data pins, ECC verification will not be performed. , this method has certain limitations; the main reason for these defects is due to the injection of ERROR outside the memory, which reduces the controllability

Abstract

The invention provides an ECC function verification method. The method comprises the following steps of constructing a verification platform and receiving a reading/writing request signal sent by the verification platform; according to the reading/writing request signal, obtaining a current address and original data corresponding to the current address; obtaining a random number by utilizing a random function, and taking the random number as an injected error number, wherein the error number is smaller than or equal to the width of the original data; and performing ECC function verification according to the injected error number. The method has the advantages of strong controllability, strong randomness, high verification flexibility and comprehensive verification functions.

Description

technical field [0001] The invention relates to the field of information technology, in particular to an ECC function verification method. Background technique [0002] ECC (Error Correcting Code, error checking and correction) technology is an error correction technology. Before the emergence of ECC technology, there was another technology in memory applications, that is, parity check technology. Compared with ECC technology, the disadvantage of this technology is that it can only find errors, but not necessarily correct them. ECC technology The emergence of ECC has solved the problem of errors in the memory and repaired the errors so that the entire system can run normally. ECC technology can only perform single-bit repair and multi-bit error detection. [0003] With the rapid development of today's IT industry, especially in the application of industrial computers and aerospace electronics, such equipment is required to maintain normal operation under harsh conditions su...
