Webfunctions can have any number of inputs but only one output. The variables declared within the function are local to that function. The order of declaration within the function defines how the variables passed to the function by the caller are used. functions can take, drive, and source global variables, when no local variables are used. WebVerilog HDL also provides few system tasks. The system task name is preceded with a $. For example, ... module will have two 4-bit input ports and one 5-bit output port.
