UDP ports rules

• An UDP can contain only one output and up to 10 inputs.
• Output port should be the first port followed by one or more input ports.
• All UDP ports are scalar, i.e. Vector ports are not allowed.
• UDPs can not have bidirectional ports.
• The output terminal of a sequential UDP requires an additional declaration as type reg.
• It is illegal to declare a reg for the output terminal of a combinational UDP
