    >Description:

    In a numerical constant, if the unsigned number is larger than
    the size specified for the constant, is the unsized number
    truncated, losing the bits on the left?

    For example, should o be assigned 1111111110 below? --

      module m ( output reg signed [9:0] o ) ;
      always begin
        o = 2'sb00000000_10 ;
        $display("|%b|", o) ;
      end
      endmodule
