FreeLists / si-list / [SI-LIST] Post route analysis in XTK

[Siva kumar <sivakumar_skm@xxxxxxxxx>]

Hi Gurus,
         Thanks a lot for your replies. I am doing
post route analysis in XTK. I am facing some problem
with XTK. There are some errors, warnings and
informational messages.
     1. Zero segment length detected (warning,Error)
     2. Network loop detected at pin (Informational
message)
     3. pin overlaps via at (x,y)on net NET1 (Error,
Warning)
     4. missing segment (segment no) on NET1.
(Error,Warning)
     5. Overlapping pads detected. (warning)
     6. duplicate segments width are different
(warning)
     And wherever the "  Network loop detected"  is
appearing, the net is shown is "PRE-ROUTE". XTK
simulation reports also shows the net status as
PRE-ROUTE. 
      Some more details :
1. Pads layout tool and Spectra auto router is used. 
2. Burried, micro and blind vias 
     In the first run itself, padsx was giving fatal
error and not allowing to proceed. By changing the
stackup definition, i was able to move to the next
step. 
     When we adjusted the Vias that were present under
the pad, errors 1,3 and 4 were mostly cleared. but
still in the qif2xtk.err file the warning is
there.Since most of these nets are shown as pre-route,
i don't know whether the layout information for these
nets are taken into consideration or not. But these
nets are properly routed. 
     our team closely working with innoveda to solve
this problems. 
     If anyone of you had already faced these problem
and solved this issue i would like to get the help
from you solve this problems.


Waiting for your thoughts,

Thanks in advance,
siva
