How to use separate configuration file in the ISE project?

[Rebecca]

I wrote a separate configuration file to tell which architecture
should be used for the component declaration (u1, u2) in the top
design. The configuration file is give as follow:

library IEEE;
use IEEE.std_logic_1164.all;
use IEEE.std_logic_unsigned.all;
use IEEE.std_logic_arith.all;

configuration cfg_entity_test of entity_test is
for entity_test_arch
for u1 : entity_u use entity work.entity_u(entity_u_arch_u1);
end for;
for u2 : entity_u use entity work.entity_u(entity_u_arch_u2);
end for;
end for;
end cfg_entity_test;

My question is how can I tell the ISE that this is the configuration
for my top design “entity_test”? I added the configuration file to the
project and it seemed that synthesis just ignored it.

Thank you very much for kind help,
Rebecca

Last time I tried, ISE would not accept a vhdl configuration
as a top entity. If this is still true, we are stuck
with using a file list instead.

Can we use the configuration file for non-top design files in ISE?
And would you please tell me how to using a file list?
Thanks a lot,

I doubt it. Try it and see:

And would you please tell me how to using a file list?

To cover verilog, synthesis accepts a top module/entity
name (ports=device pins) and a list of the hdl files
that represent the top, and the module/entity instances
that fill in the design.
Start with the new project "wizard". Good luck.
