ISE6.1: Constant definition in package doesn't work

[Erik Markert]

Hello,

I have a package with a function and some constant definitions. Now I
implement it to the project. In Modelsim I can access the constants but
in ISE6.1 Synthesis it doesn't find that constant.

Code:
package body fpga_config_pack IS
CONSTANT deviceID : bit_vector(15 downto 0):= X"0815" ;
function calc_par (SIGNAL ad: std_logic_vector ) return std_logic IS
....
END;
END fpga_config_pack;

use work.fpga_config_pack.ALL;
ENTITY ...

ARCHITECTURE rtl_A...
BEGIN
data(0) <= calc_par(address);
data <= TO_STDLOGICVECTOR(deviceID);
END rtl_A;

The Synthesize XST has no problems with calc_par() but reports an error
with the constant:
Compiling vhdl file C:/Xilinx/PCI_Card/fpga_config_pack.vhd in Library work.
Architecture fpga_config_pack of Entity fpga_config_pack is up to date.
Compiling vhdl file C:/Xilinx/PCI_Card/config_space.vhd in Library work.
ERROR:HDLParsers:3312 - C:/Xilinx/PCI_Card/config_space.vhd Line 62.
Undefined symbol 'deviceID'.

In Modelsim standalone simulation all works fine.
What's the mistake in ISE6.1?

Thanks

Erik

Your problem is consistent with ISE6.1 set to '87 instead of '93.

But constant declaration in packages should be also possible in '87? Or
is there something different in including that library?
