Description
Technical Field
The invention relates to the technical field of testing, in particular to a chip testing system, method, equipment and medium.
Background
The Web service is a distributed application software design method, can realize cross-platform, cross-programming language, low coupling, self-contained distributed application software, different software running on different network hosts, no matter what programming language, running platform and communication protocol are used, as long as the design is carried out according to the Web service, data can be exchanged arbitrarily without depending on third-party software and hardware.
With the increasing urgency of chip localization substitution requirements, numerous chip design companies emerge in the market, however, chip development features a long period, including a plurality of stages of architecture, design, test, tape-out post-test, and the like, in order to reduce the development period, researchers have designed many chip simulation test systems so that the work of chip design, verification, and the like can be executed in parallel.
The current common chip simulation test platform design method is that the whole system is divided into a front part and a back part, the front part displays a user interface and sends user operation to the back part, the back part adds hardware simulating chip behavior by using virtualization technology, then executes corresponding test flow according to a test command submitted by the front part, and returns a test result to the front part for display.
Although the chip simulation test system can test the chip, the following problems exist:
1) the system portability is poor. Since the test system is implemented based on a specific hypervisor (hypervisor), when the hypervisor is changed, all environment deployment operations such as image creation, system installation, starting, virtual machine shutdown, etc. need to be changed to a new hypervisor interface, and dynamic migration between virtual hosts is also not facilitated.
2) The system safety and reliability are poor. Because the system lacks mirror backup, dynamic migration, data and network security, state monitoring and other mechanisms and is not fully tested by internal and external users, the system is easy to develop imperfectly. For example, host storage media corruption is not considered, or anomalies that are difficult to recover are generated by internal and external attacks, such as denial of service attacks on the network, etc.
3) The system coupling degree is high and is not easy to expand. Because unified planning is not available, newly added hardware, drive and test codes are not only repeated, but also can influence the operation of the original module, and a great deal of energy is consumed to position the module conflict problem, so that many research and development personnel adopt modes of repeatedly installing virtual machines and the like to solve the conflict, and the resource consumption and environment deployment work are further increased.
