Verification system and method for memory controller

Abstract

The invention is suitable for the field of verification, and provides a verification system and a verification method for a memory controller. The system comprises a test case generator, a bus driver, a monitoring unit and a scoreboard, wherein the test case generator is used for generating at least one test case; the bus driver is used for generating a control event according to the test case generated by the test case generator, converting the test case into the interface bus timing of the memory controller and sending the interface bus timing to the memory controller simultaneously; the monitoring unit is used for monitoring a monitoring event which is generated by the memory controller according to the received interface bus timing; and the scoreboard is used for judging whether the memory controller works normally or not according to the control event generated by the bus driver and the monitoring unit monitored by the monitoring unit. By establishing a module level-based verification system for the memory controller, a plurality of channels of the memory controller are parallelly and fully verified, so the system has high reusability and efficiency.

Description

technical field [0001] The invention belongs to the verification field, in particular to a memory controller verification system and method. Background technique [0002] In modern IC (Integrate Circuit) design, especially in digital image processing modules, the required data is often larger than the on-chip storage capacity and the calculation is complex and real-time. Therefore, for a processing system with limited on-chip storage resources, it is usually necessary to borrow external storage space. In order to improve the real-time processing capability of the system, it is necessary to use Direct Memory Access (DMA) to exchange data between the design module and the external memory. The DMA controller is to control the transmission of data between the IC design module and the external memory. Due to the important role of the DMA controller in data transmission, its errors may lead to the collapse of the entire system. Therefore, it is also necessary to fully verify it. ...
