禁用协议允许外部模型参与SystemVerilog禁用处理。参与方法是通过DPI task的特殊返回值和特殊API调用来完成。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...
从Verilog到SystemVerilog的发展过程来看,两种语言都有其产生的必要性。Verilog在上世纪80年代中期产生,解决了当时一万门 以上设计面临的种种问题,Verilog的产生带来了门级设计到RTL级设计的变革,接下来的近20年,随着设计规模的扩大,Verilog也在不断的演 变和扩展,但是抽象层次始终徘徊在RTL级别;进入90年代以后,Verilog...
是的,可以在类中编写SystemVerilog断言。断言可以嵌入到类的方法或属性中,以便在特定条件下进行检查。这有助于提高代码的健壮性和可维护性,特别是在复杂的验证环境中。 74. What is an argument pass by value and pass by reference? 按值传递和按引用传递的参数是什么? 按值传递参数是指将参数的实际值复制一...

How to pass arguments by reference ? 通过引用传递的参数不会复制到子例程区域,而是将对原始参数的引用传递给子例程。参数声明前面是关键字。对子例程内变量所做的任何更改都将反映在子例程外的原始变量中。ref // Use "ref" to make this function accept arguments by reference// Also make the function au...
SystemVerilog提供了通过value 和reference将参数传递给Task 和function 的方法。 Pass by value 在Verilog 1995/2001中,可以通过值将一个参数传递给Task 和function 。此时仿真工具会对参数值进行复制。 module function_by_value (); reg [7:0] data ; ...

The SystemVerilog code below shows the general syntax we use to declare task which pass data by reference. task <return_type> <name> (ref <argument>); // task code endtask : <name> As we can see from this, when we want to pass a parameter by reference rather than value then we ...
