Help with XST warnings (2)

[morpheus]

Can anybosy help me with these warnings? I tried looking at XILINX
answers database and found no record of them.
Moreover, I found out that by modifying the environment variable, these
warnings can be turned off....but i'm kinda skeptical as i dont know if
these are major show-stoppers or not

WARNING:Xst:1710 - FF/Latch <seriesiii_chan1_reg_2> (without init
value) is constant in block <t1>.
WARNING:Xst:1290 - Hierarchical block <c1> is unconnected in block
<t1>.

Thanks

regarding the first warning, it just means that you have a bit by name
"seriesiii_chan1_reg_2" which is not changing and having a constant
value of either '0' or '1'.
the second warning says that you have one module(or port) not connected
in its instantiating module. this you have to look into if it was
purposeful or not.

Well,
Thanks for the advice, but the problem is that I can't figure out why
the block may be unconnected. I checked my code, simulation. So the
question is how do I make sure whether this warning is purposeful or
not.
Any advice is appreciated
Thanks

You have to find out if leaving c1 unconnected dosent affect the
functionality of the design.
