摘要
随着微处理器复杂度的不断提高,用全功能验证方法将花费大量的计算资源和时间。提出一种基于图模型的验证方法,首先利用功能抽象的方法得出微处理器的图模型,然后由基于图模型功能覆盖的代码生成算法生成验证代码。我们将这种方法应用于一款DSP的功能验证,结果显示在很短的验证代码激励下得到了较高的代码覆盖率。
With the continuous increase complexity ofthe microprocessor, utilizing full- function verification method will cost tremendous computational resources and time. We proposes a graph -model based verification method. First, we educe graph model of the microprocessor using functional abstraction. Then generate test code using a code generation algorithm based on the graph model. As a case study we apply this method to verify a DSP. The result shows that we can get higher code coverage at much shorter test code stimuli.
