Ultralibrarian doesn't work in searh providers

Give this a try community.cadence.com/.../search-providers-not-working

Dear sir.Need your help.

I have custom made PCB and its .brd file.I don't have its schematic.I had validate schematic and interlinked successfully with .brd file. After ECO it do not change routing but unplaced parts.Is there any way to save placement.

Thanks and regards,

Before you import the netlist changes try a File - Export - Placement, write the file out. Import the netlist then use File - Import - Placement (make sure add unplaced components is checked and also ensure that the origin you used in the export is the same on import. By default unless you have made major changes in the schematic parts shouldn't be unplaced but you say that you didn't have a schematic so if you have redrawn this there could be differences in the device name.

Thanks a lot.It worked.

No having some errors.(Routing).Seems i have to export cmg and then import to this placed version design. What do you says?

@Steve

I need your helponce again.

I have costume made .brd file i have validate(Ref des-Net name same as in schematic) it and export its changes

to board.It was linked properly.

But it unroute nets and make it dummy nets and make a new rats net.

Is there any solution to save routing.Or it can take same name as in schematic rather then dummy net.

Is there any way that dummy nets do not pupup it take same name as assigned in schematic.
