Re-compile Pcells

KishanVNs

 Hi All,

 

I have a Library of Pcells and i have done some modifications to them using db commands .

But when i am placing them in another layout , i am not able to see the changes that i did using the db commands.

I understood that i have to re-complie the Pcells[ compile to pcell not to  skill file ]. The issue is i have around 200 pcells and i want to do it automatically. I don't know what command is used for re-compling [ db command ] and not able to find it.

It would be helpful if any one could post the code for it.

 

thank you

Kishan

    Kishan,

    I believe all you will need to do is:

    cv=dbOpenCellViewByType(libName cellName viewName)
    tmpFile=makeTempFileName("/tmp/PcellCode")
    result=pcSkillGen(cv tmpFile nil)
    when(result
      dbDefineProc(cv tmpFile)
    )
    dbSave(cv)
    deleteFile(tmpFile)

    All that the graphical pcell editor does is generate the SKILL for the pcell and attach it as the pcell proc for the cellVIew - so this is in effect what the "compile to pcell" does. The functions in the above are all public.

    Regards,

    Andrew.
