SystemVerilog adds several enhancements to Verilog for representing large amounts of data. The Verilog array construct is extended both in how data can be represented and for operations on arrays. Structure and union types have been added to Verilog as a means to represent collections of variables...

function加input output 返回void Task消耗时间 Task可以有input output inout reference传的是句柄,值会变(少用),sv中function和task可以.name(wirename)传参 OOP oop将复杂的数据类型和相应的方法封装在一起 class是图纸,object是房子(实体)(通过new新建),handle是地址,properties是电灯开关,methods是开灯/关灯的操...
data_type array_id [ index_type ]; data_type是数组元素的数据类型。 array_id是要声明的数组的名称。 index_type是要用作索引的数据类型。 Queues 队列是大小可变的有序元素的集合。队列中的每个元素都由一个序号表示,该序号表示其在队列中的位置,0表示第一个,$表示最后一个。

Hi, I started to use typedef struct packed in my simulation no problems. However when I try to pass compile the and pass a struct it gives an error message. I just assumed I could pass a struct as a parameter. My workaround is to pass it as a wire ...
Read more on SystemVerilog Array Manipulation. Give an example of a function call inside a constraint. The function must return a value that can be used in the constraint expression. Here's an example: function int rand_range(int a, b); return (a + b) % 2; endfunction class ABC; ra...
特殊的返回值不需要更改SV代码中导入或导出DPI task的调用语法。虽然仿真器保证了导出task的返回值,但对于导入task,DPI另一侧必须确保返回正确的值。 对导入task的调用与对SV原生task的调用是无法区分的。同样,对代码中的导出task的调用与对非SV task的调用是无法区分的。
