Memory controller verification system, method and scoreboard

Abstract

The invention is applicable in the technical field of memory controllers, and provides a memory controller verification system, a memory controller verification method and a scoreboard. The memory controller verification method comprises the following steps of: detecting bus operations by the scoreboard according to monitoring affairs generated by monitoring a memory controller and control affairs generated by a test case generator; when a write operation is in the bus operations, writing an address in the write operation and a data corresponding to the address into a structural body of a preset type; storing the generated structural body into a queue; and when a read operation is in the bus operations and the data in the structural body stored in the queue or read from a memory is the same as the data read by the read operation, verifying that the memory controller works normally. The verification method provided by the invention can verify whether the memory controller accurately controls the memory under various bus time sequence conditions.

Description

technical field [0001] The invention belongs to the technical field of memory controllers, in particular to a memory controller verification system, method and scoreboard. Background technique [0002] With the increasing scale of integrated circuit chips, in the design of System On Chip (System On Chip, SOC) based on Intellectual Property (Intellectual Property, IP) multiplexing, on-chip bus design has become the most critical issue. For this reason, many on-chip bus standards have emerged in the industry. Among them, the AMBA on-chip bus structure introduced by ARM has become a popular industry standard. The AMBA specification mainly includes the AHB system bus and the APB (Advanced Peripheral Bus) peripheral bus. [0003] figure 1 It is a connection diagram of the main module, the memory controller and the memory, the main module and the memory controller are connected through the AHB bus, and the memory controller and the memory are connected through the memory interf...
