ICON outside of the block with ILA instance - CONTROL0 signals trimmed away

I use ISE 14.5

 

When I use ILA inside a "block_with_ILA_inside" and ICON outside this block then I get the same problem as in here

 

http://www.xilinx.com/support/answers/52789.htm

 

and the solution is exacty the same !!!

entity block_with_ILA_inside is port(
something : in std_logic;
CONTROL : inout std_logic_vector(35 downto 0)
);
end A;

and somwhwere in the top project I do:

inst : block_with_ILA_inside port map(
somehting => another_something,
CONTROL => ICON_CONTROL0_SIG);

inst_ICON : icon port map(
CONTROL0 =>  ICON_CONTROL0_SIG);

WITH read_cores set in synthesis I get plenty of:
WARNING:NgdBuild:452 - logical net 'sata_reader_sfp_sender/sniffer_gen.fifo_sender_sniffer_anal/CONTROL<12>' has no driver

LIT:243 - Logical network sata_reader_icon[10] has no load.

See Section 5 of the Map Report File for details about why the input signal will become undriven.

See Section 5 of the Map Report File for details about why the input signal will become undriven.

MapLib:979 - LUT3 symbol "sfp_reader_sata_sender/sniffer_gen.fifo_sender_sniffer_anal/U0/I_NO_D.U_ILA/U_DOUT" (output signal=sata_sender_icon[3]) has input signal "sfp_reader_sata_sender/sniffer_gen.fifo_sender_sniffer_anal/CONTROL<6>" which will be trimmed. See Section 5 of the Map Report File for details about why the input signal will become undriven.


Perhaps there could be an AR for that.

If the AR mentioned is your solution...what is the other requirement in this topic?
