AXI Crossbar design circuit verification method and system

Abstract

The invention provides an AXI Crossbar design circuit verification method and system, and the method comprises the steps: configuring design parameters and verification contents in advance, generatinga first data packet with the number of master equipment and a second data packet with the number of slave equipment, and respectively driving a first AXI Crossbar port and a second AXI Crossbar portto receive and transmit burst information, respectively monitoring the burst information received by the first AXI Crossbar port and the second AXI Crossbar port, respectively storing the burst information into the first information queue and the second information queue after the burst information is added into the identification number, and comparing the burst information with the same identification number in the first information queue and the second information queue. According to the embodiment of the invention, on the basis of the verification platform of the number of parameterized components and a full-automatic monitoring mechanism, universal, rapid, flexible, sufficient and effective automatic verification for the AXI Crossbar in a full-function mode is realized, and a large amount of manpower, material resources and time cost are saved.

Description

technical field [0001] The invention relates to the field of cross-interconnect bus design verification, in particular to a method and system for verifying AXICrossbar design circuits in a full-function mode. Background technique [0002] AXI (Advanced eXtensible Interface, Advanced Extensible Interface) is the most important part of the AMBA (Advance Microcontroller Bus Architecture) protocol proposed by ARM, and is used to describe the data transmission mode between the master device and the slave device. The AXI bus is a high-performance, high-bandwidth, low-latency on-chip bus, widely used as a bus system for SOC (System On Chip, System on Chip) chips based on ARM high-performance processors, which supports master devices and slave devices The point-to-point connection between, in order to meet the needs of multiple master devices accessing multiple slave devices, the AXI Crossbar with full function mode is designed and widely used. [0003] At present, with the continu...

Problems solved by technology

However, the existing AXI Crossbar circuit design verification method is only for a specified number of master-slave devices, and a verification environment can only verify one type, that is, each type used needs to be verified separately, and each verification It is necessary to modify the verification environment to make it suitable for the scenarios that require verification. If there are multiple verification environments, it is necessary to build multiple verification environments at the same time or continuously disassemble the verification environment for verification, instead of providing a verification method in a general sense to support Verify that any M master device accesses N slave devices

Obviously, applying the existing verification method to the verification scenario of using multiple AXI Crossbars with different M values ​​or N values ​​at the same time must waste a lot of time and consume a lot of manpower. In order to meet the current use requirements, it is urgent to provide a It is versatile and can quickly, fully, flexibly and effectively verify different M to N types of full-featured mode AXI Crossbar methods
