Problem with xilinx 12.3 Timing Analyzer

[salimbaba]

Hi,

I am using xilinx 12.3 for my synthesis and implementation. I am havin
issues running timing analyzer, the problem is that when i run timin
analyzer from the ISE Design Tools menu as a stand alone application an
open my design with .ncd file, a message pops up and says "Design is missi
for open design. Please make sure design (.ncd) is opened". I have no ide
what it means as i am openeing the design according to the procedure i rea
on some site.



Secondly, if i run it from within xilinx Project navigator-> Tools-> Timin
Analyzer->Post Place and Route, a message comes in console window at th
bottom saying



"Process "Analyze Post-Place & Route Static Timing" complete
successfully".

But i don't see timing analyzer running or anything.



Can anyone tell me how to make it work.



thanks

regards
