Unable to load flash symbol AB00

gtaylor

 ? What does this error mean? Every time i try to lay a track in editor i get error code E- (SPMHDB-274) appear in the command box at the bottom.

 I have my psmpath setup correctly in user preferences and its only just started doing it. Im using editor 16.5 btw.

 

TIA

    Chances are that you copied some of the provided symbols and associated padstacks to your own directory and removed the default paths from the PAD / PSM PATHs The provided symbols use the AB00 DRA / FSM definition from the default directory, either move the AB00 files to your directory, or edit the padstacks to remove the references to AB00, look in the "Flash" entries, remove the values and save the edited padstacks. You can fix this for just the design from Tools>Padstack>Modify Design Padstack. If you fix the padstack definitions, use Tools>Padstack>Refresh gto get the design updated.

     Perfect, thanks. There was an AB00 field in the flash entry of my VIA padstack. I removed it and saved to my directory and everythings fine.

    Hi i have the same issue. But where can i find the Flash entries for this AB00.dra symbol. This symbol looks empty to me, just has a dummy shape in it. I don't know where did it come from.

    I had this issue when i removed "$psmpath" from my list of psm paths. If you go to Setup->User Preferences->Paths->Library, click the ... next to psmpath and check if "$psmpath" is in the list. Add it if it is missing. Restart PCB editor after adding the path.

    I believe the root of this is that the AB00 flash is used in the default via located at C:\Cadence\SPB_17.4\tools\fsp\samples\dra\via.pad (your directory might be slightly different) and for me, since $psmpath wasn't in my list of psmpaths, it couldn't find where the flash symbol AB00 was located.

    This was the problem i was having and how i fixed it. Hopefully it could be helpful for someone in the future.
