$monitor用于追踪变量的变化情况。 $write的用法与$display一致,区别在于,一条$write语句执行完后,不会自动换行。 moduletop_module();regclk=0;always#5clk=~clk;// Create clock with period=10regin=0;initialbegin#10in<=1;$display("At time %d, data is
SystemVerilog提供了一个ref关键字作为函数参数的前缀。当使用ref时,表明参数是使用引用传递,'ref'语法类似C++中的引用. 有两种情况下使用'ref'做参数比较有意义。第一种情况,由于函数只能有一个返回值(不考虑传统Verilog上的input/output参数端口声明),任务没有返回值。当函数需要返回多个值或者任务需要返回一个以上...

SystemVerilog also adds a number of enhancements to Verilog tasks and functions. These enhancements include simplifications of Verilog syntax or semantic rules, as well as new capabilities for how tasks and functions can be used. Both types of changes allow modeling larger and more complex designs ...
As with functions, we must call a task when we want to use it in another part of our SystemVerilog design. The method we use to do this is similar to the method used to call a function. However, there is one important difference between calling tasks and functions in SystemVerilog. ...
