[PCB_FORUM] Re: Disconnected vias from planes - different problem

Yep, the quantities of spam and porn we see on this list are truly
staggering :)

Never mind, nothing is going to change, this will be my last post on
this <:^)

Jim,

Not wanting to continue this discussion ad infinitum, but feel compelled
to again state that the issue with allowing email onto the website is
security.  There still needs to be a log-in requirement and that creates
the extra click everyone objects to.

I have just gotten off a conference call with another community manager
for a large very well-known company.  They were allowing comments to be
posted onto their community site technical papers with no log-in
requirements.  After a very short time spammers found this capability
and used their scripts to post comments with links to porn sites.  Not
something we can allow on our community site.  

Remember that one can "subscribe" to the forum of their choice on
www.cdnusers.org and receive all postings from that forum directly to
their desktop.  The email contains a link directly to that forum post
where one can reply directly.

If one checks the "remember me" box on the log in screen, when you click
back on that link you will automatically be logged in and not have to go
thru the log in process again.

Hear hear. I think a crafty web-designer could link this email forum to
the web forum quite easily. Allow topic-specific hyper-links to the web
forum within the email forum. Just a suggestion.

Richard:
I have noticed the same problem on 15.2 as well, except you can move
_anything_ there (vias, clines, other shapes...) and have it happen
randomly.  This has mainly happened to us on large boards with lots of
nets and lots of dynamic shapes.  I haven't heard of it happening on
15.51, but we are only now rolling that out to most users due to
conversion issues with large hierarchical/module designs.

I haven't turned in an issue on it because I can never get it to repeat
so Cadence could see the problem in action and debug.


Linda:
Although your forums are fine for browsing, they don't lend themselves
to the quick answer possible on an email forum.  I can't speak for
everyone on this forum, but I don't have time to log into your forum
just to answer a question a user asks or to confirm another user's
observation.  

If you ever get your forums functioning like this one, where I can dash
off a quick message and get back to work, they will get a lot more
traffic.  It is inefficient to have to do a separate log in and reply to
and to reply to a message in a web window.  And I am sure many Cadence
employees who were previously allowed to be on this forum would agree if
they were allowed to.  IMHO, you are doing your customers a dis-service
by operating your forums in a web-only mode, but I know that is not the
primary consideration.

Richard,

Please post this note to the PCB forum on the Cadence user community at
www.cdnusers.org.  Cadence engineers monitor that site and will be able
to both see this issue you are raising, and respond.

Subject: [PCB_FORUM] Disconnected vias from planes - different problem

Hi all

I've possibly found a new serious problem with shapes.  I can't find the
exact problem in the archives, so I thought I'd throw it to you all
before I submit it as a bug.

We have a board with several negative shapes.  Upon sliding a via, all
the shapes that either are in contact with that via or void around that
via, immediately become 'out of date'.   It happens randomly.

Eg, it could be a GND via I am sliding, but all negative shapes around
that via effectively disappear, leaving only its outline.  This leaves
thousands of unconnected vias, ie unconnected nets.

That's not the problem.  The real issue is that any stitching vias on
these shapes are now disassociated with any signal.  Updating shapes
will NOT work.  The stitching vias now have a dummy net, and will stay
that way.  (By stitching vias, I mean only those from shape-to-shape.)

Funnily, if you catch it soon enough, an undo will rectify it!

We're using 15.5.1, latest ISR, etc. We also really need to keep
negative shapes, due to the size of the designs.

Any clues?  Has this been reported before?

Cheers,
Richard
