其实，老美拿着EDA搞事情，已经很多年了，之前是点对点，针对特定的国内单位和公司。 比如说，2018年， 美国 禁止 中兴 使用EDA工具。再比如， 2019年，华为海思 被列入实 体清单后，被迫切断与美国EDA公司的合作。这次就明确了针对全部中国客户。 以下文章来源于龙科多 ，作者龙科多 龙科多 . 深度科技观察，聚焦半导体、操作系统等底层技术。内容全平台发布。 今天聊聊最新的美国EDA禁令。龙科多认为，美国此举基本无法起到多少制裁作用， 利好国 产EDA发展 。但这个事，还是值得具体说道说道。 最近，《纽约时报》 等多个外媒称，美国商务部已向包括Cadence、新思科技和西门子等全 球领先的EDA公司发出通知，要求停止向中国供应EDA技术。 Cadence、新思科技 都是美国公司，西门子是德国公司。消息一出，国内还是非常关注。有 一些人士认为不大可能，认为报道不准确。 不过，外媒陆续报道 ，上述三家EDA公司都对外发布公告，表示收到了美方的通知。这下， 基本做实了。 EAD工具，主要是用于 半导体制造测试的设计和验证，以及监控性能和质量。 如果再细分， 包括 模拟IC设计与验证、数字IC设计与验证，晶圆制 ...
