ERROR (OSSHNL-109)

Hi,

No matter how many times I check and save, every time I try to generate the netlinst I get the below error. Please help me solve this.  Cadence Virtuoso version: IC6.1.6.500.1

ERROR (OSSHNL-109): The cell view, 'XXXXX_tb/schematic', has been modified since the last extraction.
Re-extract the design (File->Check and Save menu option) for schematic cell views to correct this error.

Thanks

    Hi,

    please check the cellview properties ( shift-Q) , check the "system" selector on the top and look for the modified and checked  counters.  Checked needs to equal or larger than modified
    to be valid for the netlisting. ( see picture )

    In some cases I saw problems when people running SKILL code through hooks at cell saving time which manipulates the cellview.

    Other than that it's hard to come up with a solution without more information. Sorry.

    Regards,

    Marc

    Providing some more info rather than posting on the end of an old thread would be a good start...

    Anyway, normally you'd open the problematic design and perform a check-and-save operation. Otherwise from SKILL you could do:

    cv=dbOpenCellViewByType("libName" "cellName" "viewName" "schematic" "a")
    schCheck(cv)
    dbSave(cv)
    dbClose(cv)

    Something like that. This is assuming that my guess of what you're asking is correct.

    Regards,

    Andrew.

    Hi Andrew,

    Yes.. I am expecting whatever you shared.. But in this CDF termOrder popup's opening when i am running top level cell.

    I don't want to open CDF termOrder popup's.  

    How to fix CDF termOrder without opening popup's using skill?

    Regards,

    CSR..

    Performing schCheck on a schematic should not popup anything, and certainly not anything about the CDF termOrder.

    There is an environment variable:

      envSetVal("auCore.misc" "updateCDFtermOrder" 'boolean t)

    which controls recreation of the CDF when you check-and-save a symbol, but not on a schematic. You can suppress that by using:

      envSetVal("auCore.misc" "updateCDFtermOrder" 'boolean nil)

    or

      envSetVal("auCore.misc" "queryCDFtermOrder" 'boolean nil)

    but I don't see what that would have to do with doing an schCheck on a schematic. So I suspect your code is doing something else and you've not explained the whole setup?

    Andrew.

    Hi Andrew,

    I have added the below statement in .cdsinit and opened virtuoso and ran check and save script but still CDF termOrder popup’s coming..

    envSetVal("auCore.misc" "queryCDFtermOrder" 'boolean nil)

    The find attachment is CDF termOrder popup..

    Check and Save Errors fixing Script:

    procedure(check_and_save(lib)
    let((id id1 cv)
    id = ddGetObj(lib)
    foreach(cell id~>cells~>name
    id1 = ddGetObj(lib cell)
    if(member("schematic" id1~>views~>name) then
    cv = dbOpenCellViewByType(lib cell "schematic" nil "a")
    schCheck(cv)
    dbSave(cv)
    )
    )
    t);let
    );proc

    OK, from the popup (which is not part of the standard Virtuoso software), it would appear you're using this custom code: How to update CDF terminal list automatically if pin names change?

    If it is indeed that exact code being used, then you could do:

    schUnregPostCheckTrigger('CCScheckAndUpdateCDF)

    before running your fixing code. You could first call schGetPostCheckTriggers() to see if "CCScheckAndUpdateCDF" is one of the registered custom triggers.

    Regards,

    Andrew.
