Register

### Name

Reg - Easy way to instantiate a register

### Synopsys

    netOut <= netCk.Reg ( netIn )

### Description

This method is a method of net. The net which this method is applied to is the clock of the register. The net given as parameter is the input net. The method returns a net : the output net.
Note that it is possible to change the generator instanciated with the `SetReg` method.

### Example

    class essai ( Model ) :

      def Interface ( self ) :
        self.A  = SignalIn  (  "a", 4 )
        self.S  = SignalOut (  "s", 4 )

        self.Ck = CkIn ( "ck" )

        self.Vdd = VddIn  ( "vdd" )
        self.Vss = VssIn  ( "vss" )

      def Netlist ( self ) :

        self.S <= self.Ck.Reg ( self.A )

### Errors

Some errors may occur :

- `[Stratus ERROR] Reg : The input net does not have a positive arity.`
  The input net must have a positive arity.
- `[Stratus ERROR] Reg : The clock does not have a positive arity.`
  The clock must have a positive arity.
