WebOne thing that has been explained to me that the SystemVerilog has two properties associated with a signal, its "type" and its "kind." The "kind" is the familiar Verilog "reg", "var" or "wire". The "type" is the data type, 4-state "logic", 2-state "bit", integer and real. You can leave out the "kind", as long as you have specified the "type".
