The reason for this restriction is that we are allowed to hierarchically reference the arguments of a task/function as static variables, which are initialized to be zero or specified initialized values at the beginning of the simulation, from the outside of that task/function, and that would no...
Default values in structure expressions some or all members of a structure can be assigned a default value A structure expression can specify a value for multiple members of a structure by specifying a default value. The default value can be specified for all members of a structure, using the...
