WebApr 6, 2024 · In addition to this, we can also use the SystemVerilog default keyword inside our array literal. We more typically use the default keyword inside of SystemVerilog struct types which we will talk about in a future post. However, we can also use the default keyword as a convenient way to assign the same value to every element in a static array. WebArguments can have default values; You can skip arguments by leaving that position empty, even if it doesn't have a default value. See what `test2(,,) prints out in example 2. Check out `debug1 and `debug2. If your argument is a string, then the decision of whether you need to enclose the argument in double-quotes depends on where the argument ...
