Hi allI've possibly found a new serious problem with shapes. I can't find theexact problem in the archives, so I thought I'd throw it to you allbefore I submit it as a bug.We have a board with several negative shapes. Upon sliding a via, allthe shapes that either are in contact with that via or void around thatvia, immediately become 'out of date'. It happens randomly.Eg, it could be a GND via I am sliding, but all negative shapes aroundthat via effectively disappear, leaving only its outline. This leavesthousands of unconnected vias, ie unconnected nets.That's not the problem. The real issue is that any stitching vias onthese shapes are now disassociated with any signal. Updating shapeswill NOT work. The stitching vias now have a dummy net, and will staythat 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 keepnegative shapes, due to the size of the designs.Any clues? Has this been reported before?Cheers,Richard
I have had this problem before on older releases but
I seem to remember it hapened also with other operations such as
move. Since I started using dynamic shapes for all my shapes I
have not seen it. Are your negative shapes dynamic or static. Either
way it still sounds like a bug to me.
Richard,I use stitching vias all the time and yes I have seen the issue where the vias become disconnected from the associated net.After much stress, I decided to generate a small shape inside the via boundary which is attached to GND then copy the via/shape around the design. Cadence added the "Retain Net of Vias" checkbox to the Copy command which seems to leave the via associated to the net but in some cases it loses its association. Whatever we do it will be a Band-Aid.If this issue has not been reported before maybe it should.. I would certainly jump on board to support the PCR by adding my company to the list.Mike CatramboneUTStarcom, Inc.
Richard,Please do contact customer support and let them troubleshoot the issue with you. This is the recommendation to me from a couple of Cadence engineers.Linda
Hi This was addressed in the latest hotfix, and it seems to have been fixed. (To my own understanding and trialing, it was related to the Esc key being aliased to the Oops function; I'll explain no further.)Thank you to the people in Cadence.Cheers,Richard
