XST Timing report

Hi,

I am using ISE5.1i...XST synthesis tool.

At the end of synthesis, XST generates defualt timing report for 1 or
2 paths.

How can i generate a timing report after synthesis for more than 100
paths?

ie., as like .twr after Place and route.

And How can i measure the time dealy between 2 specific points...
Points could be FF,mux or any logic

Thanks in advance.

Regards,
Muthu
