但如果你使用32比特的表达式,把结果保存在32比特的变量里,与一个32比特的变量进行比较,或者使用适当的with表达式,SV都会在数组求和过程中使用32比特位宽。 SV没有提供专门从数组中随机选取一个元素的方法,所以对于定宽数组、队列、动态数组和关联数组来说,可以使用$urandom_range($size(array) - 1),而对于队

int array[8][4] ; // 紧凑的声明 1. 2. 如果代码试图从一个越界的地址中读取数据,那个SV将会返回数组元素的缺省值。对于一个元素为四状态类型的数组,例如logic,返回的是X,而对于双状态类型,例如int或bit,则返回0。这适用于所有的数组类型,包括定宽数组、动态数组、关联数组和队列,也同时适用于地址中含有X...
