Problems solved by technology

However, the random control of the operation variables is basically carried out by random constraints in the uvm_item module, because the invalid random variables generated in the random process are huge, and it will consume a lot of simulation time and computing resources to complete the effective random operation data. As a result, the verification efficiency is low and the resource consumption is serious

Embodiment 1

[0053] see figure 1 , figure 1 It is an implementation flowchart of a verification method driven by UVM function coverage in an embodiment of the present invention, and it is applied to a UVM verification platform. The method may include the following steps:

[0054] S101: Collect pre-generated random variables.

[0055] When using the Universal Verification Methodology (Universal Verification Methodology, UVM) verification platform to verify the function of the algorithm module, the pre-generated random variables are collected, for example, the pre-generated random variables can be collected through the monitor in the UVM verification platform.

[0056] S102: Determine whether there is a random variable in the variable queue, if not, execute step S103, and if yes, execute step S104.

[0057]Create variable queues in advance for storing non-repeating variables. After collecting the pre-generated random variable, judge whether the pre-generated random variable exists in the ...

Abstract

The invention discloses a verification method based on UVM function coverage rate driving. The verification method is applied to a UVM verification platform. The method comprises the following steps: collecting a pre-generated random variable; judging whether a random variable exists in the variable queue or not; if not, verifying the target algorithm module by using the random variable; if yes, removing the random variables; obtaining a target coverage rate of the current verified random variable in a preset variable range; judging whether the target coverage rate reaches a preset coverage rate or not; if not, repeatedly executing the step of collecting the pre-generated random variables until the preset coverage rate is reached; and if yes, determining that the random verification of the target algorithm module is completed. By applying the verification method driven based on the UVM function coverage rate, the verification efficiency is improved, and operation resources are saved. The invention further discloses a verification device and equipment driven based on the UVM function coverage rate and a storage medium, and the corresponding technical effects are achieved.

Description

technical field [0001] The present invention relates to the technical field of software testing, in particular to a verification method, device, equipment and computer-readable storage medium driven by UVM function coverage. Background technique [0002] With the development of computer technology, computers replace manpower to perform many calculation tasks. After developing an algorithm module, it is necessary to verify the function of the algorithm module. The verification of the algorithm module has always been a difficult point in the verification. Unlike the control module, the verification of the algorithm module does not require the association of data before and after the same operation unit. Each operation data is independent of each other. However, due to the huge amount of data, most The calculated data must be covered to ensure sufficient verification of the algorithm module. [0003] At present, the popular algorithm module performs algorithm operation through...
