case () inside gives errors with ncvlog

Hi,
The following code gives an error with ncverilog. Can any one figure out why ? (version 12.2)

case (ratio) inside
	     [990 : 1010] :  mon_txn.bit_rate_captured  = 3'b000;
	     [390 :410]   :  mon_txn.bit_rate_captured  = 3'b001;
	     [190 :210]   :  mon_txn.bit_rate_captured  = 3'b010;
	     [90 : 110]   :  mon_txn.bit_rate_captured  = 3'b011;
	     [35 : 45]    :  mon_txn.bit_rate_captured  = 3'b100;
	     [16 : 24]    :  mon_txn.bit_rate_captured  = 3'b101;
	     [8 : 12]     :  mon_txn.bit_rate_captured  = 3'b110;	     
endcase



(1)case (ratio) inside 

   ncvlog: *E,ILLPRI: illegal expression primary [4.2(IEEE)]

(2) [990 : 1010] :  mon_txn.bit_rate_captured  = 3'b000;

	               |

    ncvlog: *E,NOTSTT : expecting a statement [9(IEEE)]

(3) [390 :410]   :  mon_txn.bit_rate_captured  = 3'b001;

	     |

     ncvlog: *E,ILLPRI : illegal expression primary [4.2(IEEE)].

(4)  [390 :410]   :  mon_txn.bit_rate_captured  = 3'b001;

	             |

      ncvlog: *E,NOTSTT : expecting a statement [9(IEEE)].

and so on

Seems that 'case (...) inside' is a SystemVerilog 2012 construct (I don't have an SV 2009 standard to compare). It's working starting with version 13.10. If you can't migrate, you'll have to rewrite your code.

It is in SV-2009 also.
