Description

technical field [0001] The embodiments of the present invention relate to the field of chip technology, and in particular to a chip circuit function verification system, method, device and storage medium. Background technique [0002] In chip design, functional verification of chip integrated circuits in software application scenarios can test the core functions of chips in the early stage of circuit development, which is an essential link to ensure the success of chip design. With the emergence and development of ultra-large-scale chips such as 5G and artificial intelligence, the testing scale of chips in software application scenarios is becoming larger and more complex.

AI Technical Summary

Problems solved by technology

[0004] However, the method provided in the above-mentioned prior art has the following defects: First, the verification work cannot be carried out before the specification of the application scenario is completed, resulting in insufficient mobilization of the human resources of the verification personnel

Secondly, verifiers need to collect and understand scenario information and manually write verification incentives based on the scenario information, resulting in a long verification cycle and a large manual workload

At the same time, when the verifier understands the application scenario specification, due to the complexity of the application scenario information, it is easy to cause the written verification incentives to deviate from the software application scenario

In summary, the chip circuit function verification method provided by the existing technology is difficult to realize the verification of large-scale application scenarios
