基于UVM实现随机测试的先进方法

随机设计越来越复杂，受约束的随机化测试方法已成为验证的发展趋势。本文以数据流交叉模块的验证为例，介绍如何基于UVM验证方法学构建受约束的随机化测试平台，其主要内容包括：UVM验证平台的建立、受约束的随机的实现、功能覆盖率的实现、自动检查结构等方面。

Advanced Methods to Achieve Random Testing on UVM

As designs grow larger, it becomes more difficult to create a complete set of stimuli needed to check their functionality.The solution is to create test cases automatically using constrained random tests（CRT）.In this paper, we take data switch module for example,describes how to build constrained random test platform base on UVM verification methodology, its main contents include：UVM Test-bench establishment, implementation of constrained random, functional coverage achieved,automatically checks and so on.
