Found an interesting (frustrating) issue when one changes between netlist
and synchronizer updates to PCBs.
Following suggestions from a day or two ago on how to get changes
straightened out when the synchronizer tries to keep track of original
component links, I used the netlist clear and then import a new netlist into
the PCB to straighten out the netlist connections. This occurred when I
copied already placed components in PCB to place a similar grouping of the
same components, renamed them within the PCB to match the target netlist
component designators, and tried to get the design synchronized. The
original problem was that the synchronizer remembered the original PCB
component designators and couldn't handle the correct manner of matching the
newly designated PCB components. After loading the netlist to the PCB to fix
this problem I cannot use the synchronizer because it still hasn't sorted
out the component matching. I get two lists of non-matching components and a
matched list which contains no matches. Worse then even that the two lists
of components needing matching do not have even half the components listed
in them and there are no components in either list which can be matched by
the designators. There is not one single matching pair of designators in the
reference or target lists.
This is just a general warning or heads up about this issue.
However, does anybody know a manner of getting these matches corrected and
sorted out?
I did try exporting the schematic, exporting a ver. 3 PCB (I figured a ver.
3 PCB file might free up the P99SE component matching) and bringing them
into a new database. This didn't work. I get exactly the same matching
results from the synchronizer.
I finally made a copy of the PCB within the same database using paste
special and then deleted the original design. Then I could easily match the
components (C1 ... C1_1, U3 ... U3_1, etc.). But there has got to be a
better way.
