Re: [PEDA] Updating PCB designators
Re: [PEDA] Updating PCB designators
Andrew, when I first looked in these Forum I run in the name synchroniser to. Meanwhile I discovered (hope I´m right?)it means the server that apears in Protel99SE when you chose update|schematic in PCB, or update|pcb in Schematic. Like Robi just answered (greatings to australia;-) ) you can use tool|annotate to change the designators in PCB and then use the synchroniser to synchronise it with the schematic. Hope it helps Waldemar Forgive me if this subject has been done to death. If so, please offer me some pointer to a repository. I'd like to change the designators on my PCB to make it easier to find components on the board. There's been some talk about a synchroniser, but I've found the discussion confusing because there's nothing I can immediately see is called a synchroniser under the Protel menus, and because I've not joined the threads from the beginning. Presumably there is more than one way to do this, and judging from Protel's track record one of these methods is more reliable than the other. I'd like to change the designators so they read in some kind of ascending order from say, left to right across the board. Any advice gratefully received. -- Andrew Ircha * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/proteledaforum@techservinc.com * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

don't forget to update the schematic after re-annotating. this caused a large headache for me in the past. trying to help people learn from my mistakes Chris Hower DPS Telecom CAD,Technician (559)455-1600 Ext. 136 www.dpstele.com -Original Message- From: robi artwork [mailto:[EMAIL PROTECTED]] Sent: Monday, October 29, 2001 3:53 AM To: Protel EDA Forum Subject: Re: [PEDA] Updating PCB designators From the main menu: Tool Re-Annotate This will give you the 4 options, available - to sort your designators a certain way Robi Artwork - PCB Design Bureau PO-Box 199,Lot 33 Jamaica Drive Deception Bay Q4508Australia -- C/o Robi Bittler Ph: 07-3203 0634 Fx: 07-3203 3958 - only on request * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/proteledaforum@techservinc.com * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

Just to clarify a possible misunderstanding, if the links are re-established through reference designators after a renumbering but before the information has been transfered, you will have one big mess. I generally do not recommend renumbering for several reasons, but this is a controversial subject, some people insist that renumbering is very useful. My own view is that there are better ways of accomplishing the same goal: ease of interpretation and identification of components by assembly and service personnel.

I'd like to change the designators so they read in some kind of ascending order from say, left to right across the board. Any advice gratefully received. 1) The synchronizer is a pair of processes that you can use to exchange info between Sch and PCB. It extends the facilities of the old netlist load (which still exists). It appears in your Sch menu as Design|Update PCB, and in PCB as Design|Update Schematic. It works by associating a hidden handle with each Schematic component and PCB footprint. These hidden handles are then used to match sch component with a PCB component - regardless of changes to the designators etc. When you first try to update a PCB from a Sch you will be prompted to match sch components by PCB component - create the initial match. You have the opportunity to change the match and to manually match components which do not have then same designator. The system automatically initially offers a match based on designators. If you use the Update PCB process to load in components into a PCB then the match is obviously made automatically. 2) Before re-annotating in the PCB it is strongly recommended that you set up the hidden handle match by running the synch - this will save you a lot of work in manually matching. Then you can safely re-annotate as many times as you like before back annotating the Sch (using the Design|Update Schematic process). When back annotating the sch it is useful to know that footprint and comment changes are transferred back to the sch but it does not transfer back any netlist info (i.e. changes to pin connections). I use the update sch to transfer all the bottom side (wave) footprints to the sch to ensure complete match - that is when I design the sch everything has a reflow footprint, as the PCB design progresses it is sometimes necessary to flip a component(s) to the bottom side. On a wave/reflow PCB this may entail using different footprints for top and bottom, the Update Sch process helps keep everything in match. I use the synchroniser exclusively (and have since it was introduced) to do the initial load of the footprints into the PCB. In the old days of netlists and no hidden handles, it was necessary to immediately run the back-annotate command when a PCB re-annotate was done to ensure the all important was-is file was current. This was a pain. 3) as others have mentioned there is a re-annotate process in PCB that can do the re-numbering. There have been some reports on this list of some problems with the designator ordering, I think. I can't recall the details. 4) when you run the synch you may find that you see a whole lot of hatched rectangles on your PCB. These are rooms and can be deleted if you do not wish to use the rooms feature. Bottom line - you will get an easier result by making sure your Sch and PCB are matched through the synch before doing your PCB re-annotate. Do this by running Design|Update PCB. It is very instructive to check the Preview changes button so you can see (and edit/delete) the macros that will be run over the PCB. Also, think carefully about which options you want to include. Delete Components (removing footprints not in the Sch design) may not be what you want if you have mechanical parts that you have not exploded - they will get removed. The assign net to connected copper option can really slow down the update. There is more that could be said but that is enough from me I think, Ian Wilson * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/proteledaforum@techservinc.com * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
Re: [PEDA] Updating PCB designators
Apparently there are hidden handles which link the PCB and schematic parts, and that works fine for reannotating as long as you keep it open. But when you close and reopen, it reestablishes those links via the reference designators. Steve Hendrix I missed this on first reading. This is not actually the case. For synchronising, the hidden handles are persistent. It is during Export-To-Spread and any subsequent Import-From-Spread that the handles are valid only for a session, and hence the session must be kept active. This is not the case for the synchronizer.
