Updaing schematic component breaks Library link to IntLib

lamabrew

I'm hoping this is pilot error on my part.  Here's how to get in to this situation:

 

  1. have a schematic open with a component that needs a change
  2. use inspector and see what library the component is in
  3. open .LibPkg that has the component in it
  4. select its .SchLib and pick part in the SCH Library dialog that needs editing
  5. recompile the .LibPkg (to create updated IntLib)
  6. after editing, right click the part in the SCH Library dialog and select update schematic as otherwise the schematic doesn't know the part is updated ( ignoring for now the problem that there's there no way to know what other schematics need updating...)
  7. in the schematic the library link is now to the SchLib, not the IntLib.
  8. so CS thinks the schematic and PCB are out of sync
  9. if you try and open the PCB and go update the schematic from the PCB (which is still linked to the IntLib) CS won't do anything because it doesn't think that's a difference in the reverse direction

 

Only way I have been able to fix this is select each part one at a time in the schematic and edit the library file name back to the appropriate IntLib.

 

How do you update without breaking the library name, etc?

    I believe CS will use the first matching component name from the libraries it scans. It could be by opening up the IntLib you are creating a SchLib file that is being detected first. Do you need to use IntLib libraries as it can be simpler to stick with SchLib and PcbLib if you are needing to make changes.

    Hi Peter,

     

    All of my libraries are IntLibs - I can't imagine trying to keep track of things where the schematic symbol and footprints are decoupled from each other.

     

    When I place the component there's no problem, CS uses the IntLib library link (name) in both the schematic and layout.

     

    It's when the IntLib component is edited (i.e. the underlying .SchLib is changed) that CS breaks the link to the IntLib doing the component update.

     

    Is there some way/configuration option to tell CS that IntLibs should take priority?  (and shouldn't that be the default?)

    This could just be a case of IntLib libraries are really designed to be 'read only' and are not expected to change and thus no simple mechanism for updating and applying those updates to existing schematic or PCB documents. I'm not sure why you think it would be difficult to use separate SchLib and PcbLib libraries - the names of the libraries can be the same and much easier to edit and then update open documents. In fact I would consider having the separate files much easier to work with because there is no having to have lots of projects just to be able to update IntLib files.
