Hi everyone
Cadence found the problem, it was autosilk generation that was making the
problem.
After setting the autosilk to none on all and deleting the autosilk layer
contence the problem was solved.
Autosilk is off in a new board but is typical on when copying and existing
board.
Clearly an error but until they fix it everyone needs to know.
Thanks for everyones help.
Hi
Peter

Peter,
Sorry that my alternatives don't shed any new light.
You are probably correct in thinking it is something underlying in the
database.
Traditionally Cadence has always had more in-depth versions of
DBFIX/DBDOCTOR
that they can run an get error codes from. Hopefully they will find your
error.
