如果你的代码试图从一个越界的地址中读取数据,那么system verilog将返回数组元素类型的缺省值。也就是说,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。这适用于所有数组类型。 很多system verilog仿真器在存放数组元素时使用32bit的字边界,所以byte,shortint和int都是...
In SystemVerilog, it is recommended that two enumeration literals don not only differ in case. For example, enum (item, ITEM) is not a good choice of item names. These names create confusion among design users and it is more difficult to pass parameters from case-insensitive HDLs, such as...
javaenum中Parameterexpected javaenum中Parameterexpected ## 引言 在Java编程中,枚举(enum)是一种特殊的数据类型,用于定义一组预定义的常量。枚举类型可用于表示一组固定的值,例如星期几、月份或是一组状态等。在使用枚举时,有时会出现“Parameterexpected”(预期参数)的错误。本文将介绍该错误的常见原因、如何解决以...
If the Quartus® Prime software does not recognize the parameter value type, the software sets the parameter type as untyped. The Quartus® Prime software supports the following parameter types: Unsigned Integer Signed Integer Unsigned Binary Signed Binary Octal Hexadecimal Float ...
