摘要： 目前集成电路的模拟电路在数字验证期间大多采用行为级模型（Behavior Model）的形式进行基本的连接性的验证。但随着当今世界在集成电路方面的电路的复杂度越来越高，规模越来越大，SoC或者MCU集成的模拟模块也越来越多，越来越复杂，数模验证的复杂度剧增。大部分公司对于数模交互的功能、时序等只能等到回片测试才能验证设计的正确性。阐述了一种基于Wreal model的数模混合验证的方法，用来实现数模交互的大部分功能的可验证性，提升验证的完备性，以及完成数模电路间时序的验证等。

Platform implementation method for hybrid digital-analog verification based on wreal model

Abstract： At present, most of the analog circuits of integrated circuits use behavior-level models to verify the basic connectivity during digital verification. However, as the complexity and scale of circuits in integrated circuits in the world become higher and larger, there are more and more analog modules integrated by SoCs or MCUs, which are becoming more and more complex, and the complexity of mix-signal verification has increased dramatically. For most companies, the function of digital-to-analog interaction, timing, etc., can only wait for the return test to verify the correctness of the design. In this paper, a hybrid mixed-signal verification method based on wreal model is used to realize the verifiability of most functions of mixed-signal interaction, improve the comprehensiveness of verification, and verify the timing between mixed-signal circuits.
