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:

Perhaps there could be an AR for that.
