Data types can be used to declare data objects or to define user-defined data types that are constructed from other data types. ? integer types ? 2-state - can simulate faster and take less memory: shortint (16-bit signed), int (32-bit signed), longint (64-bit signed), byte (8-...
21,The simplest interface is just a bundle of nondirectional signals. Use logic so you can drive the signals from procedural statements. 22,The modport construct in an interface lets you group signals and specify directions.仅仅是interface的一个子集而已。 23,you should always declare your program...
`define增强SystemVerilog中扩展了`define的功能,代替了宏定义的功能。 3.2.1 字符串中的宏变元替换(Macroargument substitution within strings)Verilog的`define宏定义中可以用( ” ),则引号中的文字变成了文字型字符串。 这就意味着,Verilog不能建立含有宏变元的字符串。 如下例所示,不能按原本意愿展开。 `defin...

However, changes in the implementation should not be visible as changes of "kinds" definition. When writing a token oriented parser, you may want to assign a type to a token like NUMBER, SYMBOL, SEPARATOR, STRING-LITERAL, ... You can define them as you want. They should be used in ...
STRING without FS has a value 1234 ncsim: *W,RNQUIE: Simulation is complete. If the user string matches, but the format specifier is wrong for the kind of data that is being passed in as an argument, you'll get a runtime error. For the above example, use+define+RUNTIME_ERRas a ...
