The invention discloses a method for verifying an IP core, a device and a system thereof. The method comprises the following steps: generating test data through a control board card; sending the test data to a verification board card, so that the verification board card performs read-write access operation on the target memory based on an IP core in the verification board card and the test data; obtaining first data read by the verification board card from the target memory; and obtaining a verification result according to the test data and the first data. The test data is generated in the control board card, and the verification board card is controlled according to the program in the control board card to realize read-write verification of the IP core, so that the defects of long development time and poor flexibility caused by the fact that hardware verification personnel need to write a hardware verification language in traditional IP core verification are avoided, and the verification efficiency of the IP core is improved.
Description
technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a method, device and system for verifying IP cores. Background technique [0002] Double Data Rate Synchronous Dynamic Random Access Memory (Double Data Rate SDRAM, DDR SDRAM) is a new type of memory chip developed on the basis of SDRAM chip, which is called DDR for short. The biggest feature of DDR is that it has a double data transmission rate, that is, data transmission can be performed on both the rising and falling edges of the clock. DDR has experienced several generations of development, from the initial DDR1 to DDR2, DDR3, the transmission rate and storage capacity have been continuously improved. [0003] The IP core is usually used to control the DDR memory for read and write operations. At present, the verification of the IP core is generally realized through simulation and testing with a verification system. The specific process refers to the simulation ...
