check the instance symbol change in schematic

I realize this topic is quite old but I'm trying to do the same thing. I open a cellview for read and need a skill function to determine if it requires check & save for any reason. Has anyone figured this out and care to share?

Thanks,

Hi Phill,

Well, dbIsConnCurrent() will tell you if the cellView has been modified since it was last "extracted" (i.e. the last check). To see if there are any symbols which have been modified since the last time it was checked, use:

modifiedInstHeaders=setof(instHeader cv~>instHeaders instHeader~>masterChangeCount!=instHeader~>master~>modifiedCounter)

From this you can glean the libName/cellName (and instances) which would give you a warning in the CIW or show with markers had you opened the schematic in edit mode. What the incantation above does is check if the record of the last modifiedCounter on this schematic for each master instantiated matches the current state of that master.

This worked perfectly for me. Thank you for the quick help!

Hi Andrew,

I was trying to get a notification email  about the symbols updated since last time it was checked, For that i was first checking which all symbols was updated using

modifiedInstHeaders=setof(instHeader cv~>instHeaders instHeader~>masterChangeCount!=instHeader~>master~>modifiedCounter). 

I got an error - *Error* eval: unbound variable - cv

Please help me how to proceed.

Hi Amlu,

cv is the variable that stores the CellView database ID, so you need to have defined it earlier, the above is just a snippet. example:

cv=dbOpenCellViewByType("libName" "cellName" "viewNamw")

modifiedInstHeaders=setof(instHeader cv~>instHeaders instHeader~>masterChangeCount!=instHeader~>master~>modifiedCounter). 

Hi,

I tried using below lines:

cv=dbOpenCellViewByType("libraryName" "cellName" "viewName")
modifiedInstHeaders=setof(instHeader cv~>instHeaders instHeader~>masterChangeCount!=instHeader~>master~>modifiedCounter)

I get  'nil' all the time, even if there is updated version of the symbol have been checked in.

Is the libraryName cellName and viewName  on the first line for the schematic view that contains the symbols? The idea is that it will check if any of the symbols used in that schematic have been changed since the last time the schematic was "checked". 

You can't just give it the lib/cell/view of a symbol view - that makes no sense.

I'm trying to guess what you might have done wrong...

Andrew.

Hi Andrew,

You are right, I was giving the viewName of symbol instead of schematic viewName. I corrected, now i could see 'nil' if symbols in the schematic remain unchanged  and some database ID if symbols are changed.
Is there a way where i could get a notification whenever symbol is checked in? I need to update port list of behavioral model whenever corresponding symbol gets updated. Can you suggest me how can i proceed.

Hi Amul,

You should probably contact the provider of your design management software. Given that you may have some complex multi-site DM setup (I have no idea) - but even if it's another user on the same network - there would need to be some trigger in the DM software to send notifications to interested parties when checkins are performed. Potentially that could be written using ddRegTrigger (with the "PostCheckin" event) but that probably depends on whether it's using a GDM integration or not and whether the checkin is performed using the Virtuoso API. Even then you'd have to write the code to send a notification (whatever form that takes).

So best to speak to your DM provider because there may be some functionality built-in to their solution that already allows a notification.

Andrew.

Hi Andrew,

Thanks for the information. I will talk to DM provider. 
Appreciate your time in responding me.
