Serious problem with XST - Matthias Alles - 2006-02-27 03:23:00

Hi,

I encounter a serious problem with xst when I try to synthesize a 
design. The design consists of several components that synthesize fine 
for themselves. However when I want to synthesize the top entity, that 
only plugs the simple components together, xst fails during the low 
level synthesis without giving me any reason WHY synthesis failed.
It's the same for ISE 6.3, 7.1 and 8.1.
Is there a way to find out why xst fails, something like a debug or 
verbose mode? Or has anyone an idea how to isolate the problem?

Thanks in advance!
Matthias

There must be some error message.Can you display
them?

Actually there is none. Just "XST failed".

How about connecting one module at a time and synthesize it? That way,
you will know which module causes the problem.

XST can fail that way if output files are
read-only (XST can't
overwrite them).
